1.0 Scope
This ASE-1019 User’s Manual gives an overview of the hardware and software design and describes
module installation, configuration, alarms, and operator control and status capability.
2.0 Operational Overview
The ASE-1019 is an ASE light source providing a typical output power of +19 dBm. It is one of the
series of amplifier/light source modules which are designed as user-friendly, compact, portable,
cost-effective solutions for use in a variety of applications. A detailed block diagram showing the
internal hardware connectivity of this chassis is shown in Figure 2.0-1.
An Ethernet communications hardware interface is provided to allow the ASE-1019 to be
controlled via a 10/100BaseT link using either Static or Dynamic IP addressing. In this
configuration, a standard HTML browser (e.g. Firefox, Chrome, Internet Explorer) provides the user
interface and the various control and status HTML pages are integrated into the microcontroller’s
firmware. A +5V AC/DC adapter is provided to power the module.
In addition to the Ethernet GUI, the ASE-1019 can be connected directly to a Windows based
computer which runs the USB graphical user interface (GUI) software. This GUI also provides
complete control and status of all amplifier and optical power monitoring functions.
The output optical power level is measured using a 1% tap to minimize insertion loss. An onboard
temperature sensor allows the power monitoring circuitry to be calibrated during production test
to provide measurement resolution of 0.01 dB and linearity (relative accuracy) of 0.1 dB over an
operating temperature range of 0°C to 40°C.

The GUI application has an additional optional feature which allows the user to perform time
stamped data logging. This option includes capturing the input and output optical power levels as

7
well as the corresponding amplifier bias current, operating modes, temperature, LOS level and
alarms, and writing this information to a .csv file.
2.1
Default Operational Settings and Non-Volatile Memory
The ASE-1019 module always saves the last operational state in non-volatile memory regardless of
whether the USB GUI or the Ethernet interface is used for control and status. All changes to any
control parameters are automatically saved in non-volatile memory and recalled whenever the
module is powered on.
The ASE-1019 module is shipped from the factory with the default settings given in Table 2.1-1.
This module is setup to be “ready for operation” as soon as it is powered on with the bias current
set to achieve the advertised output power so the module can be placed directly into service
without changing any parameters if desired.

4.0 Optical Safety
4.1
National Standards
United States Government safety requirements for lasers and laser amplifiers are described in the
DHHS/CDRH radiation performance standards, 21 CFR 1040.10 and 1040.11. International safety
standards for lasers and laser amplifiers are described in the IEC-60825-1:2007 document.
4.2
Class 1M Source of Optical Radiation
The ASE-1019 delivers invisible laser radiation with fiber-coupled output power of up to 135 mW
(21.3 dBm) and as such are Class 1M sources of optical radiation. This module includes the warning
information as shown in Figure 4.2-1 as part of its label to make it easily identifiable as a Class 1M
source. Internally, the module contains one 980-nm laser-diode pump.

P
out
max: 135 mW 1520 –1620 nm
Figure 4.2-1 - ASE-1019 Laser Radiation Safety Label for Class 1M Laser Product
ASE-1019 Safety Specifications:
1) Wavelength range: 1520 to 1620nm (invisible, infrared region).
2) Beam size: The beam is normally safely confined within a single-mode optical fiber with a
mode-field diameter of about 10-um.
3) Beam divergence: If the beam is allowed to escape into free space (e.g. by not connecting an
optical cable to the input or output connectors, with the dust caps removed), the beam
divergence is given by the numerical aperture of the optical fiber, typically 120mrad (half
angle).
4) Maximum power: The maximum output power (in the form of amplified spontaneous
emission (ASE)) of this module, in the absence of an optical input, is less than the Class 1M
limit of 135 mW (21.3 dBm). This power can be emitted from the output connector (ASE
power emitted from the input connector does not exceed Class 1 limits.). With a saturating
input signal of 0 dBm (1mW), the maximum output power of the module is also less than
135 mw (21.3 dBm).
4.3
Connecting Optical Cables
Optical connections to the module are made via FC connectors. The supplied dust caps should
always be left on the connectors when not in use. These dust caps not only keep the connectors
clean, but they also protect the user from any optical radiation that may emanate from these
connectors.
4.4
Eye Protection
Under normal operating conditions, with an optical cable connected to the output, or with the
dust caps on both FC connectors, there is no optical radiation emitted into free space. Therefore,
no special eye protection is required. It is recommended that optical connection or disconnection
to the module be carried out only with the optical output disabled using the GUI.
5.0 USB GUI Software Installation and Initial Power-On
This paragraph describes the USB GUI installation and power-on procedure so if only the Ethernet
interface is planned to be used, please skip to paragraph 6.0.
5.1

Main Menu as highlighted in Figure 7.2.1-1.

16
Figure 7.2.1-1 - Critical Status Area of the Main Menu, in both dBm and Watts
The key ASE-1019 module parameters of output status, output power, bias current, and
temperature are obtained from the module (by the external computer) and displayed in
prominently in this central area of the window.
The optical output power is monitored using a 1% tap to minimize insertion loss. The calculated
value is displayed in its designated location and can be shown in either dBm or Watts based on the
user’s selection of Units. It should be noted that if the output is disabled, the output power
monitor will display -35 dBm.
A temperature sensor is mounted on the PCB and its value in degrees Celsius is continuously
updated on the display.

This amplifier module can operate in either Automatic Current Control (ACC) or Automatic Power
Control (APC) mode as selected by the user from the appropriate dropdown menu. When ACC is
selected, the user must enter the target bias current setting which ranges from 0 mA to the Bias
Current Limit shown in the lower-right corner. Once the user types in the target bias current and
presses Enter, the module is commanded to provide that specific bias current to the amplifier as
shown in Figure 7.2.2-2. The internal amplifier has a bias current setting accuracy of ±10% so the
bias current displayed in the main menu can have a variation of up to ±10% compared to the user
entered bias current setting.
Figure 7.2.2-2 - ACC Mode with a User Entered Setting of 475 mA for the Bias Current
When APC mode is selected the user must enter the target output power setting in units of dBm.
An example of APC mode is shown in Figure 7.2.2-3, in this case the user has entered a target
output power of +18.0 dBm.
Figure 7.2.2-3 - APC Mode with a User Entered Setting of +18.0 dBm for the Output Power

18
The Module Fault Status indication is shown in the GUI window as well as the LED located on the
top side of the module. The Module Fault Status is a logical OR of several alarms which are laser
bias current exceeds the maximum current limit, laser pump temperature out of valid operating
range, laser driver current limit reached, and laser driver junction temperature limit reached. If any
of these conditions occur, the Module Fault Status indication will alarm (Red). These four
conditions indicate a problem with the laser and will cause an automatic laser shutdown (ALS). To
clear an ALS condition, the user must click the Reset Fault button. If the fault condition will not
clear, please contact us (TPC) since a hardware failure may have occurred.
8.0 Ethernet Browser GUI Operation

Figure 8.1.1-2 - Optical Control and Status Page
The key ASE-1019 module status parameters of bias current, maximum bias current limit, output
power, and temperature are obtained from the module and displayed in prominently in the upper
area of this window.
The total optical output power is monitored using a 1% tap to minimize insertion loss. The
calculated value is displayed in its designated location and can be shown in either dBm or Watts
based on the user’s selection of Units. Figure 8.1.1-3 shows Watts being selected by the user and
the appropriate output power level being displayed.

If the output is disabled, the output power monitor will display -35 dBm. A temperature sensor is
mounted on the PCB and its value in degrees Celsius is continuously updated on the display.
This amplifier module can operate in either Automatic Current Control (ACC) or Automatic Power
Control (APC) mode as selected by the user from the appropriate dropdown menu. When ACC is
selected, the user must enter the target bias current setting which ranges from 0 mA to the Bias
Current Limit shown in the second row of status. Once the user types in the target bias current and
presses Enter, the module is commanded to provide that specific bias current to the amplifier as
shown in Figure 8.1.1-4. The internal amplifier has a bias current setting accuracy of ±10% so the
bias current displayed in the first row of status can have a variation of up to ±10% compared to the
user entered bias current setting.
User selects ACC from
dropdown menu, enters
desired bias current,
475 mA in this case, then
presses Enter
