High power Laser Diodes Pulsed Power Supply combines laser diode driver and two independent thermoelectric controllers.
It is designed to provide pulsed and continuous modes of operation for laser diode modules used both independently or as a source of diode pumping for solid-state lasers (DPSSL) in the laboratory, medical and technological laser devices and complexes. The power supply is controlled from a computer via VLC software.
