High efficient Laser diode driver with TEC controller
The device is designed to drive and control pump laser diodes for fiber amplifiers in LIDAR and communication applications. This high high efficient laser diode driver is capable to drive Laser doides with local or remote adjustable 0 - 1,3A constant current. The TEC element controller is capable to keep the TEC and therfore the diode temperature constant up to 0.0001 K.
