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.

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.

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.
2.1.1 Definition of equipment and document symbols and designations
Do not operate the TLS-EQ-77H if the covers are removed or is defective in any way. Contact Energetiq if
any problems with the equipment are suspected.
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 or the Controller. Dangerous invisible infrared laser
beams and hazardous voltages exist inside the Lamp. Opening the chassis both voids the warranty and
exposes the user to dangerous radiation and hazardous voltages.
CAUTION: controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
WARNING: Invisible laser radiation avoid eye or skin exposure to direct or scattered radiation
Class 1 laser product

Alternating current
The TLS-EQ-77H is a Class 1 Laser Product. All appropriate laser safety measures should be in place
before operating the system. Consult your facility's laser safety officer. Laser protective eyewear should be
worn at all times while operating the system.
For further safety information, refer to ANSI Z136.1 Standard for Safe Use of Lasers, available from Laser
Institute of America (www.laserinstitute.org).
2.2. Laser Information
The TLS-EQ-77H uses a patented* laser drive system to excite a plasma that radiates in the UV as well as
the visible bands. A class 4 laser is located in the Lamp House enclosure. The optical configuration of the
Lamp House ensures that the direct laser beam cannot exit the unit. The EQ-77 laser product is designated
as Class 1 during all normal operation.
The parameters of the non-accessible internal laser are given below in Table 1.

No regular maintenance is required for the TLS-EQ-77H. Any service to the system must be performed only
by factory authorized and trained technicians. To avoid injury, under no circumstances should the user
open or modify the Lamp House or Power Supply Controller enclosure.
The unit must not be operated if the covers are removed or it is defective in any way. Contact Energetiq if
any problems with the equipment are suspected.

2.4. Safety Interlocks
The TLS-EQ-77H is equipped with interlocks to prevent operation of the device when any of the following
conditions are present:
•An external interlock is open
•No bulb is installed
2.5. External Interlocks
External interlock pins are provided for the customer’s use. Any suitable normally-open contact or solid-
state switch can operate the interlock circuit. The contact or switch should be rated for 80mA minimum at
5VDC.
The interlock circuit must be connected to enable the operation of the unit. Should the interlock connection
open during operation or standby, the source is immediately disabled, and all light output from the aperture
ceases.
2.6. Correct disposal of the unit
When the TLS-EQ-77H has finally been removed from service, observe all local environmental regulations
for proper disposal.
3. Preparation of System
