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.
