Abstract

AlGaAs/GaAs quantum cascade lasers are coherent electromagnetic wave emitting sources operating in the mid and far infrared. They provide large optical power and are characterized by small sizes. Unfortunately, partly because of their large thermal resistivity they need to be powered by pulsed generators witch provide high current value and have small rise and fall times. A solution of this disadvantage is presented in this paper as a programmable regulated current source ZS62 that uses a novel way to generate ultra fast current pulse and has its own dedicated software.
