Laser Diode Controller(DLC)
The MOGLabs Diode Laser Controller
provides everything needed to drive your
tunable external cavity diode laser (ECDL),
and lock it to an atomic or other frequency
reference.
It offers a combination of impressive
performance and ease-of-use: ergonomic
and low-noise analogue controls, and
intuitive front-panel selection of the signals
you need to monitor.
Features
Intuitive controls with logarithmic response
Auto-lock to centre of oscilloscope trace
Two oscilloscope trace selector switches
Eight functions in one unit:
Ultra low noise current source
Temperature controller
Photodetector
Demodulator (lock-in amplifier)
Feedback servos
Piezo drivers
Modulator driver
Sweep ramp generator
Applications
Laser cooling and trapping
