1 THE 11SOLO2 SINGLE CHANNEL LASER POWER/ENERGY METER
1.1 Introduction
To obtain the full performance from the 11SOLO2, we recommend that you read this manual carefully.
The 11SOLO2 is a microprocessor-based power and energy meter that uses the latest technology to
provide a multitude of options in a user-friendly environment. It is a complete power and energy meter.
The 11SOLO2 provide a statistical analysis of your measurements. It allows you to store data on the 1-
megabyte flash internal memory. Moreover, the 11SOLO2 can be updated over the internet by
connecting the USB or the RS-232 port to a personal computer.
The 11SOLO2 has enhanced network capabilities that take further advantage of the USB and RS-232
ports for data acquisition and remote control. It can transfer data files to a PC for more sophisticated data
analysis and respond to commands through the PC interface. You will find an easy-to-use
communications software to transform your PC screen into a virtual 11SOLO2 on our website.
There is no need to enter the head specifications when connecting the new Standa power or energy
detector heads, for heads version 4 and above. The 11SOLO2 is already internally set up to accept all
the Standa wattmeter and joulemeter heads with a DB-15 connector. When connecting a 11QE-xx-x-MT
or a 11XLE-4 the 11SOLO2 enters in the metallic mode to ensure proper measurements. The metallic
mode is available on all 11SOLO2. The new 11SOLO2 also has improved performance in joulemeter
mode that allows 2 additional lower scales.
Although the default parameter is Watt, you may also choose to measure in dBm.
dBm = Log (power in Watts/0.001W)
Unpacking
Each Standa 11SOLO2 is thoroughly tested and calibrated prior to shipment.
Visually inspect every 11SOLO2 unit after removing it from the shipping containers. If you see any
damage, retain all packaging materials and shipping receipts. Any damage claim should be made
promptly to the transportation company. Notify the nearest Standa representative concerning the claim,
so that any repair or replacement can be arranged as soon as possible.
Easy software upgrade
Keep in touch with the latest improvements to our user-friendly software. You can download the latest
software version anytime from our website www.standa.lt and install it on the 11SOLO2 with the serial
interface. You will find all the necessary information on downloading and upgrading in section 4.2.

call Standa or your local distributor if extra power supplies are
needed.
Input voltage required: 9 VDC/800 mA. For an input of 11 to 15 volts the battery will not
charge, but the monitor will work. If input voltage is between 15 and 25 volts the monitor will
switch to USB power or battery power. If the input power is above 26 volts either the internal
fuse will blow or depending on voltage level and waveform it may damage the monitor.
2- USB INTERFACE CONNECTOR:
Standa Ltd. All rights reserved

11SOLO2 User’s Manual Revision 0.9 11
This interface allows remote control and data transfers between the 11SOLO2 and a
computer that has a USB communication port.
3- SERIAL INTERFACE CONNECTOR (RS 232):
This interface allows remote control and data transfers between the 11SOLO2 and a
computer, a terminal, or any device that has a serial communication port.
4- 0 to 1 VOLT ANALOG OUTPUT:
For monitoring laser average power or energy by using external equipment such as a chart
recorder, a computer with an analog interface, a voltmeter, etc.
The output signal represents the amplified and anticipated power detector response in the
case of a power measurement. In the case of an energy measurement, the output signal is a
DC voltage representing the pulse energy value.
The 1 V value corresponds to the full scale reading of the selected range. That provides the
best signal-to-noise ratio. The measured power or energy is then related to the output voltage
and to the selected range according to the following equations:
selectedRangeofMax


outputVPower
selectedRangeofMax


outputVEnergy
For example:
1.00 V corresponds to 10 Watt on the 10 W range
0.25 V corresponds to 2.5 Watt on the 10 W range
0.10 V corresponds to 30 milliwatts on the 300 mW range
Specifications:
Maximum output voltage: 1 V
Output impedance: 10 k
Connector type: Female 1/8” jack
5- PROBE INPUT JACK:
The 11SOLO2 uses a DB-15 female connector to mate with the detector heads (probes).
The 11SOLO2 works with all Standa detectors. It automatically recognizes every power
detector head, which ensures accurate auto-calibration. More importantly, it can take
advantage of our Personal wavelength correction™. It reads the memory in the Smart
Interface connector (version 5 and higher) to provide a wavelength correction that is based on
spectral data measured from that specific detector.
The 11SOLO2 may not recognize some of the earlier heads. These are identified as
“wattmeter.”
Energy detector heads prior to version 4 have a BNC connector. The user must use a
universal BNC/DB-15 adaptor to connect an energy detector head to the 11SOLO2. This
adaptor is compatible with all the Standa pyroelectric joulemeters except the EPD.
For these early energy detector heads, a pop-up menu asks the user to select the proper
detector model. This does not affect the reading and the measured value is still valid.
Power detectors of version V2 and higher and Energy detectors of version V4 and
higher are equipped with an “intelligent” DB-15 male connector that mates directly to the DB-
15 female connector. They do not require an adaptor.
Standa Ltd. All rights reserved

11SOLO2 User’s Manual Revision 0.9 12
WARNING: This DB-15 connector, though similar to that of the former TPM-310 and TPM-330
monitors, is incompatible with the power detector heads of PS-310 Series Version 1
and PS-330 Series Version 1. These heads used a different technology and do not
have the same pin-out configuration.
A V1 to V2 adaptor can be used in order to connect the power detector heads of PS-310
Series and PS-330 Series Version 1 and 2. Please contact your local Standa distributor or the
nearest Standa office for further information.
Any attempt to modify connectors of the early version heads to mate with the 11SOLO2 can
result in damage to the monitor.
2 Getting Started
This section contains important information concerning the installation and operation of the 11SOLO2.
The 11SOLO2 is delivered ready to use. Just insert a detector head in the Probe Input Jack (#5 in
Figure 1-2) and press the I/O key.
2.1 How to use the keys to access the menus
The powerful CPU of the 11SOLO2, combined with the WindowsCE operating system, provides easy
and intuitive access to all of its functions. This user-friendly Windows-based interface is controlled by
four Arrow keys, an key (Enter key) and a Menu key. For users familiar with Windows, it works as
any Windowsmenu, with the ALT key being replaced by the Fkey.
Pressing the Fkey (see Figure 2-1) provides access at any time to the menu bar and, from there, to the
five main menus. Use the Left and Right arrow keys to go from one menu to the next. The selected
menu drops down to show its options. Use the Up and Down arrow keys to select the desired item from
the menu. Once the desired item is highlighted, press the Enter key to activate the function. When a
menu option has an arrow “X” at the end, pressing Enter or the Right Arrow Key “t”opens a
submenu where you can select the function. For example, in the case of the Setting menu, first select
Corrections with the Down Arrow key, followed by the Enter or the Right Arrow key “t” to access
the submenu. Move to the desired option with the arrow keys and press the Enter key to activate.

2.2 Quick power and energy measurement procedure
This section applies to all 11SOLO2 versions. It will show you the fastest way of making a laser power
and energy measurement with the 11SOLO2 and a Standa power or energy detector.
The monitor automatically recognizes all the Standa power heads and energy heads of version 4 or
higher. All custom technical data required for optimum operation of the detector will be automatically
downloaded from the EEPROM in the DB-15 connector. This data includes sensitivity, model, serial
number, version, wavelength correction factors, and time response. The 11SOLO2 doesn’t support
energy detectors before version 4.

11SOLO2 User’s Manual Revision 0.9 14
Version 7 energy heads
These heads have been calibrated with and without the attenuator at a chosen wavelength. When the
connector is attached, a message appears, asking you if the attenuator is in place. If the attenuator is in
place, the wavelength menu disappears. If no attenuator is in place, the wavelength menu appears. The
attenuator switch is a toggle switch. Select Ctrl / Attenuator to turn it on or off. See Appendix A for more
details.
Quick power and energy measurement procedure:
1- Install the power or energy detector head on its optical stand.
2- First, slide the connector latch to the right to unlock the connector.
3- Turn the 11SOLO2 off and connect a version 5 (or higher) power or energy detector head to
the 11SOLO2 using the PROBE INPUT JACK (see Fig. 1-2). It is recommended to turn the
11SOLO2 off before connecting a new head in order to prevent any lost of information from the
detector head EEPROM.
4- Slide the latch to the left to lock the connector into place.
5- Switch the 11SOLO2 ON using the I/O key.
6- Power heads will default the 11SOLO2 to power measurement; energy heads will default the
11SOLO2 to energy measurement. The monitor will default to autoscale. If you have a
photodiode, to obtain measurements in dBm, select Settings / Power Unit / dBm.
7- Remove the head’s protective cover.
Put the detector head into the laser beam path. Leave it there for a few minutes, until the
detector has reach an equilibrium temperature. The entire laser beam must be within the
sensor aperture. Do not exceed maximum specified densities, energies or powers. For the
most accurate measurement, spread the beam across 60% to 80% of the sensor area.
Attention: Power heads can be used with both CW and pulsed lasers.
- Energy heads can only be used with pulsed lasers.
For power heads, go to step 8. For energy heads, go to step 11.
Adjusting the zero (steps 8 to 10)
8- Block off laser radiation to the detector.
The power read by the 11SOLO2 when no laser beam is incident on the detector may not be
exactly zero. This is due to the fact that the detector is not thermally stabilized OR there is a
heat source in the field of view of the detector when you turned on the 11SOLO2.
9- To reset the zero, wait until the reading has stabilized and select Zero Offset in the
Ctrl (Control) menu. Then select Rezero. You are now ready to make an accurate
measurement. To turn the Zero Offset off, select Off, to reselect the previous offset, select
Undo.
10- To set the diode to zero, select Ctrl / Set Diode Zero, and press the Enter key. A message
appears requesting you to put the black cover on your photodiode and press the Enter key
after you have done so. The 11SOLO2 passes through all the scales to determine the zero
diode for each scale. The message “Diode Zero Done” appears when the 11SOLO2 has
determined the zero diode.

• Refer to specific power detector documentation for complete installation and operating
instructions.
• The power detectors are thermal sensors sensitive to temperature variations.
For high-precision measurements, it is recommended to:
• Allow the power detector temperature to stabilize before zeroing the 11SOLO2.
• Do not touch the detector head when handling the power detector. Touch only the stand.
• Avoid forced airflow or drafts around the detector.
11- Apply the laser beam to the detector head.
12- The laser beam average power or energy will be displayed in three ways for your
convenience:
a. Digitally for real time measure.
b. On a digital needle for an easy visualization of the laser beam power variation
during laser fine-tuning.
c. On a histogram to allow the laser beam’s long-term stability to be evaluated.

2.3 Description of the top level 11SOLO2 menus
This section describes in detail the first group of menus essential to the 11SOLO2 operation. Refer to
Figure 2-3 for a schematic view of the menu structure. The menus differ depending on the type of head
that is plugged in. The display menu lets you view your measurement in various ways. The scale menu
allows you to fix a specific measurement scale instead of autoscaling. Use the settings menu during
setup to set the best parameters for the measurement task at hand. They provide the flexibility to
accommodate a wide variety of measurement conditions. The more active controls you are likely to use
during your measurements are in the CTRL menu. They are described in Section 2.4.

2.3.1 Displays
The various displays offered by the 11SOLO2 allow you to quickly view your measurement in several
different ways. You will appreciate the easy-to-view high resolution 58x38 mm graphic, the LCD display
and the backlight for use in poor ambient light conditions. The display menu includes five options, (see
Figure 2-3) that allow you to select the best way to display the measurement according to your specific
needs. You can switch from one option to another without interfering with the measurements.
2.3.1.1 Real time display
This display is automatically selected when a head is connected to the 11SOLO2. The top and bottom of
the screen shows important settings so you see the conditions as well as the measurement. (see Figure
2-4). The Power or Energy Digital display is presented in giant format for easy reading in all conditions.
Directly below, the Bargraph display, as wide as the screen, presents the measurement in an analog
format, very useful for rapidly varying values. On the upper left part of the screen, you can read the Type
of Head and, under the Bargraph, the current Scale. At the bottom of the screen the leftmost box
contains the actual power or energy received by the head before any correction factors are applied. The
center box gives the resolution and the rightmost box displays the wavelength. The resolution is the
smallest increment that the current value may change on a given scale. The wavelength value tells you
what NIST-based calibration factor is active. You can find the factors on the Calibration and the Personal
wavelength correction™ certificates that are shipped with your detector.

With a 11SOLO2, you can also choose either the high resolution mode for the most significant digits
available or the standard resolution to filter out unimportant fluctuations in measurement. This is a setting
in the control (Ctrl) menu of the 11SOLO2.
2.3.1.2 Histogram display
The histogram option gives a quick look at the laser beam’s long-term stability and trends. The histogram
adds new data points at a rate of 3 Hz and is dynamically scrolled to the left for each new point as soon
as it reaches the right side of the screen.

2.3.1.4 Statistics display
In Statistics display mode, the statistical analysis screen pops-up on top of the Main display. This screen
(Figure 2-6) gives a complete statistical analysis of the measured data. See section 2.3.3.3 for a detailed
description of each item. Select the Start button to start or restart the data sampling and statistical
calculations. Use the Stop button to stop the data sampling and statistics before you reach the end of
the selected sampling time. (See Data Sampling section 2.3.3.3.) The last statistical values calculated
remain on screen so you can view them later, even if you close and reopen the Statistics window. To set
the data to zero, select Reset. To restart the data sampling, select Start. The Close button closes the
statistics window so you can see the Main display again but does not interfere with the statistics being
computed. The data sampling and statistical calculations continue with this window closed or open, and
no matter what display you select. You can open and close the statistics display window to check on the
statistics as often as you like.
The values in this display provide an additional digit of resolution to allow you to benefit from the
improved precision of large samples. You must understand your sample size well enough to know if this
additional digit is significant.

2.3.1.5 Peak Power Display
In Peak Power display mode, the pulse energy measurement of the energy mode is converted to its peak
power (watts) and is inversely proportional to the pulse length. This function is active only in energy
mode. The user must enter the pulse width, in picosecond to millisecond units using Settings/Peak
Power in the Settings menu.

2.3.1.6 Status display
The status display mode shows all the major adjustable parameters currently active for the detector head
in one convenient place, (see Figure 2-7).
Fig. 2-7 Status display
2.3.1.7 Avg Display
Fig. 2-8 Wattmeter data sampling menu
For Power Detectors:
In the Avg display mode, the power measurement is the average value defined in the data
sampling menu. You can change your data sampling to your desired average time parameters.
Statistics always run in the background in this mode. This mode is a real time average of a group
of data defined in the data sampling setting. For optimum averaging, when measuring the
average power of a pulsing laser, it is preferable to use a sample period that is a multiple of your
laser repetition rate. For instance, if you are running at 1 Hz, use a sample period of 1,2,3 etc…
seconds. If it is at 1.5 Hz, use 3, 6, 9 etc… seconds, as the sample period. You don’t need to
change the sample Rate of 10 Hz in this mode. Set the scale higher then your maximum
unfiltered measurement because. Take note that if one data point is out of the current scale, the
resulting period average will be OUT.
