1550nn DBR Laser diode Driver


LD-PD's compact DBR Laser Diode Driver is a compact all-in-one unit designed for convenience of use, and combines a user interchangeable mount for our DBR laser diode, a current driver and a TEC controller, all in a self-contained enclosure.Also we include Grating current interface and Phase current interface.This product includes a USB port and a software control application with a graphical user interface (GUI) for real-time device monitoring, control and data logging.

This Driver is used with either a 14-pin butterfly mount (provided with Type I, Type II and custom pin out routing boards) . The mounts are user-interchangeable and are sold separately from the base unit.
