1. Introduction
The TLS-EQ-77H Laser Driven Tunable Light Source is a compact, highly stable tunable light source. It
utilizes the Energetiq EQ-77 Laser Driven Light Source® as a broadband light source. A monochromator is
used to select the desired output wavelength. The monochromator output is fiber coupled to the TLS-
EQ77H output.
The TLS-EQ77H system consists of a Power Supply Controller unit, Lamp House unit, Remote Control Unit,
Monochromator Power Supply, and interconnecting cables. Connections to AC power, nitrogen purge gas,
and cooling fluid are required for operation.
For additional information contact Energetiq Technology Technical Support Services at [phone]
X111 or e-mail: [e-mail]
2. Safety instructions
2.1. General Precautions
The output beam from the TLS-EQ-77H should be blocked when not in use with an electronic shutter or
other appropriate beam blocking device. Due to the possibility of generating ozone with some models of
TLS-EQ-77H when ambient oxygen is exposed to short wavelength light, the beam should always be
enclosed in an appropriate beam pipe, tube, or enclosed space. We suggest purging any beam transport
space with dry nitrogen gas.
The TLS-EQ-77H source must also be cabled correctly and connected to a power source with a protective
earth ground prior to operation.
Refer to the Installation section of this manual in Section 4 for details of the facilities connections.
There are no user-serviceable parts inside the TLS-EQ-77H. For any problems encountered during
operation, please contact Energetiq Technology for assistance. If there is a component failure, do not
attempt to open the Power Supply Controller or Lamp House enclosure of the TLS-EQ-77H.
The TLS-EQ-77H utilizes a quartz lamp containing a high-pressure gas fill. Explosion of the lamp
and possible injury from flying fragments can occur if the lamp is mishandled.
Do not open the enclosure of either the Lamp House or the Power Supply Controller. Dangerous
invisible infrared laser beams and hazardous voltages exist inside the Lamp House. Opening the
chassis both voids the warranty and exposes the user to dangerous radiation and hazardous voltages.
This AC cord supplied is for the TLS-EQ-77H only. This AC cord cannot be used with other electrical
equipment.
The power shutdown mechanism of this laser unit is the AC power plug. Do not arrange the
equipment in such a way that it becomes difficult to connect or disconnect the AC power plug.

2
WARNING: This unit emits ultraviolet (UV) radiation that is harmful to humans. Avoid exposure
to the direct or reflected output beam. Make certain that the appropriate output beam shields and
optics are in place prior to energizing the unit. All interlocks must be satisfied prior to operation;
failure to do so may lead to hazardous conditions.
CAUTION: The TLS-EQ-77H emits dangerous levels of UV radiation. Even short exposures to
skin or eyes may cause burns. Ensure that only authorized personnel are in the vicinity of source
during operation. Personnel in vicinity of operating source should wear protective eyewear,
clothing, and gloves. Lighted UV warning lights and signs posted on doors to lab areas may help
prevent accidental exposure.
WARNING: The TLS-EQ-77H utilizes an internal Class 4 IR laser capable of causing severe injury
to eyes or skin. Do not open or attempt to service this unit. Contact Energetiq regarding any
problems with the unit.
WARNING: When working near the emitted light, always wear protective devices (conforming to ISO
4007/4849/4850/4854/4855 or equivalent regulations). The lamp installed in this housing emits intense ultraviolet rays,
which are harmful to the eyes and skin. Looking directly into the emitted light or allowing the light to fall on the skin will
damage eyesight or cause skin burns.
WARNING: If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment
may be impaired.
The power supply must be properly grounded by the outlet to prevent electrical shocks.
Securely plug in the power supply connector to avoid looseness or play. Loose connections may result in
faulty operation.

4. TLS-EQ-77H Setup
4.1. Connections
Installation of the TLS-EQ-77H consists of connecting electrical, water, and purge gas supplies, and
connecting the Lamp House module to the user’s equipment. Read "Installation Procedure" first before
making any connections.
4.1.1 Electrical Power
The TLS-EQ-77H requires 100 – 240 V~, 50/60 Hz input voltage. Power consumption is 350 W maximum
during normal operation. Some OEM versions have higher current requirements.
4.1.2 Purge Gas
Purge gas required for operation. With no purge, ozone will form from atmospheric oxygen and attenuate
the light output in the 220 – 280nm band. In addition, atmospheric oxygen and water vapor will attenuate
the output below 200nm.
The purge port fitting is a push-to-connect type, sized for 4mm O.D. tubing.
Clean and dry nitrogen from either a Dewar or research-grade N2bottle is recommended. Do not use any
other purge gas. Grade 6 or better gas purity is recommended to maintain cleanliness of the optics, and
gas should be filtered to <5um. Supply pressure should be 20 psig (0.14 MPa). With a 20 psig inlet
pressure, the EQ-77 will consume approximately 0.5 slm of flow.
4.1.3 RS-485 Interface
Connector J2 is a standard 9-pin male d-sub. Mating connector is a standard 9-pin female d-sub (for
example, AMP part no. 205203-3 with contacts 1-66504-0). See Section 10.4 for pin connections.
Port settings are 9600 bps, 8 data bits, 1 stop bit, no parity, no handshaking.
Installation of the EQ-77 consists of connecting electrical, water, and purge gas supplies, and connecting
the Lamp House module to the user’s equipment. Read "Installation Procedure" first before making any
connections.

11
4.2. Installation Procedure
1. Place the Power Supply Controller on a stable surface. The Power Supply Controller must be placed
within 2 meters of the Lamp House due to the length of the interconnecting cable. See drawing Section
10 for dimensional details.
2. Connect the Lamp House unit optical output to the user equipment using a suitable SMA fiber optic
cable.
The Lamp House should be mounted in the orientation shown in Figure 3, with the lamphouse
horizontal resting on its rubber feet. The lamp has been factory aligned in this position. Mounting the
lamp in a different orientation will cause the plasma position inside the bulb to shift slightly and may
cause performance variations.
See Section 10 for dimensional drawings of the Lamp House.
3. Connect the black 21-pin mixed D-sub interconnect cable from the Power Supply Controller to the
Lamp House. This cable must be connected before AC power is applied to the Power Supply
Controller.
4. Connect nitrogen purge gas to the Lamp House.
Clean and dry nitrogen from either a Dewar or research-grade N2bottle is recommended. Do not use
any other purge gas. Grade 6 or better gas purity is recommended to maintain cleanliness of the optics,
and gas should be filtered to <5um. Supply pressure should be 20 psig (0.14 MPa). With a 20 psig inlet
pressure, the TLS-EQ-77H will consume approximately 0.4 slm of flow.
Be sure that the nitrogen source is connected to the upper fitting on the Lamp House. This fitting
contains a flow restrictor to limit gas flow to the necessary level.
5. Connect cooling fluid to the Lamp House.
Care must be taken when making connections to avoid damage to the fittings and tubing. Two
wrenches must always be used – one to hold the fitting body, and another to tighten the nut. See Figure
4.
To make the connection: first insert tubing into the fitting and tighten the nut finger tight. Then, tighten
the nut 1-1/4 turns from the finger-tight position, using two wrenches as shown.

12
Figure 1: Water fittings
6. Connect the Remote Control Unit to the I/O connector on the Power Supply Controller using the
supplied cable. The Remote Control Unit is shipped with an interlock jumper plug installed. To use the
remote interlock function, connect a remote contact or solid-state switch across pins 1 and 3. Mating
connector is a standard 3-pin mini-DIN, CUI Inc. part no. MD-30 or equivalent. See Figure 5 for pin
connections.

7. Alternately, connect user’s control system to the I/O interface connector. See "Signal Connections"
below.
8. If using the optional RS-485 interface, connect the host computer to the RS-485 connector on the
Power Supply Controller.
9. Connect the host computer to the Monochromator control connector on the Lamp House using a
suitable USB cable.
10. Connect the external Monochromator power supply to the Monochromator power supply connector on
the Lamp House.
11. Connect AC input power source to the Power Supply Controller.
The system is now ready to operate.
4.3. Chiller Information
The system must be connected to a cooling system. See Section 8 for information on the recommended
chiller.
5. TLS-EQ-77H Operation
5.1. Startup
Once the lamp is set up properly, verify that all personnel that will be in contact with the lamp system are
aware of the potential hazards involved. It is the responsibility of the user to verify that the lamp is being
used safely.
This example assumes the use of the EQ-99-RC Remote Control Module to provide local control. If using a
custom control system, substitute the appropriate digital input and output lines from Section 10.3 for the
switches and LEDs described below.
1. With the EQ-99-RC Remote Control Module connected properly, review the status LEDs on the
Power Supply Controller. The POWER ON LED should be lit, and neither the CONTROLLER
FAULT nor LAMP MODULE FAULT LEDs should be lit.
2. Turn on the OPERATE Switch (place switch in UP position).
3. Within several seconds the LASER ON LED will light. Laser light is now present in the Lamp
House.
4. In approximately 20-150 seconds the igniter will be turned on automatically and the plasma will
ignite. The LAMP ON LED will be lit. The duration of the warm up time (20-150 seconds) will
depend on the temperature and previous operating condition of the EQ-77. The EQ-77 will
automatically detect when the unit has reached the optimum conditions for ignition.
5. If a bulb fails to ignite within 150 seconds after the OPERATE switch was activated, the LASER
ON LED will go out, the LAMP FAULT LED will be lit, and LAMP ON LED will remain off. This is
very unusual. However, if this occurs, turn the OPERATE switch to the OFF position (down) and
begin at Step 1 again. If this occurs multiple times, contact Energetiq.

14
5.2. Stopping
To turn the LAMP off, simply turn the OPERATE Switch to the OFF position. If the lamp will not be used for
some time, the AC supply can be turned off.
To minimize wear on the ignition components, it is best to avoid frequently starting and stopping the lamp. It
is recommended to run the lamp continuously if long off-periods are not required.
5.3. Monochromator Interface
The monochromator is controlled through its USB interface. A simple Windows application is available to
communicate with the monochromator from a host PC, and control the basic functions of the instrument.
To use the application:
1. Download the file "MH1034_Installer-Package_Aug-24-2016.zip" and extract the files to a new folder.
2. Run "MH1034.exe" and follow the prompts to install the application.
3. Connect the monochromator to the host PC USB port.
4. Run "MH1034App.exe" to launch the application.
The Windows .dll installed by the installer can also be used to write custom control software. Refer to the
document "MH1034 Mono DLL Description Jul-28-2016.pdf" for a description of the software interface.
6. Service Requirements
