Description
4.1 Chapter overview
This chapter gives a basic description of the Quan-
tum Cascade Laser Starter Kit system and its com-
position.
4.2 System Composition
The Quantum Cascade Laser Starter Kit is made
up of the following items:
(1) Laborator y Laser Housing (LLH1 00)
(2) Temperature Controller (TCU151)
(3) QCL pulse switching unit (LDD100)
(4) QCL pulser timing unit (TPG128)
For operation of the system, the user must pro-
vide a stabilized DC power supply capable of de-
livering DC current tha t corresponds to the laser
peak current multiplied with the specified duty cy-
cle at the specified LDD100 voltage: refer to the
datasheet of the laser.
CAUTION !
Do not lift TCU151 or TPG128 only on the top
cover, since this might loosen the connection be-
tween the cover and the chassis.
