Abstract

Using of single semiconductor element containing multiple quantum well saturable absorber both for mode-locking and as passive negative feedback element in the resonator of flashlamp pumped Nd:YAG laser is reported. In the Q-switched and mode locked regime of generation, 40 ns long trains containing 5 pulses (at FWHM) were generated; the energy of the whole train was 1.5 mJ, single pulse duration was 50 ps. In the regime of passive negative feedback the pulse trains were stretched to 160-280 ns, and effective pulse shortening along the train from 50 ps to 25 ps was observed.
