Description:
The laser controller has two temperature controllers
capable of sub-mK stability
precision current source based on the Libbrecht-Hall
circuit. The laser controller is designed for very fast
current modulation via the servo input enabling high-
speed servo control of the laser's frequency. The
current servo input can accommodate input
frequencies over 10 MHz and is limited by the 1 kΩ
input impedance. Additionally, an RF port is available
for higher frequency modulation.
The range of pole settings for the
T2 temperature control loop
(diode temperature control) for
D2-105 Laser Controllers with
Serial Number 2675 and higher
(Temperature Control Board
Serial Number 6987 and higher)
have been modified to allow the
user to more easily control a low
thermal mass laser assembly
such as a Photodigm TOSA.
Please use the appropriate
instructions in the "Tuning the
Temperature Controller" section
of this manual for your Laser
Controller and laser type.
Always power down the D2-105
