It is a very compact module with mounting sockets for butterfly laser diodes. This pulsed laser diode driver with integrated TEC controller delivers precision pulses which are generated internally by an on-board AWG (Arbitrary Waveform Generator).


It includes many functionalities like gain switch suppression or pulse delay generator.  It is an interesting alternative to EOM (Electro-Optics Modulators) or AOM (Acousto-Optics Modulators). See our fiber modulation tutorial for more information.


Applications of this pulsed laser diode driver includes high energy laser seeding, LIDAR testing, etc.


The GUI software lets the user have total control of all module functions and AWG. A “.csv” file can be used to enter complex shapes. It includes several libraries for software integration (Labview VIs, DLLs, Hexa etc.).


This pulsed laser diode driver works alone or in series with other products in our range like:

Complex systems, such as fiber lasers, can be quickly developed on this module platform.
