Abstract

A compact laser diode based transmitter was designed and tested for laser radar and various laboratory applications. Single optical pulses with a peak power of up to 200 W, 23 - 65 ps pulse duration and a repetition rate of up to 50 kHz were measured. Transient mode spectral filtering suppressed afterpulsing modes by a factor of 10⁴ - 10⁵ with respect to the peak power. A control module was developed which provided a jitter value between electrical triggering and the optical pulses as low as 14 ps. Averaging of 10³ events allows 1.5 ps stability between the triggering and the optical pulses to be achieved within a delay range from 5 to 250 ns.
