Abstract:This paper presents a microsecond, high current pulse generator to drive quantum cascade lasesrs. The driver systems consist of pulse generator; power amplifier; fast switches and constant current supply circuits. The pulse width and pulse repetition rate are varied from 1μs to 100μs and 1 kHz to 2 kHz, respectively. Pulsed peak current could achieve 2.2 ampere. The whole systems are of great value to be employed to drive quantum cascade semiconductor diode lasesrs.
