Abstract

We demonstrated that a simple flashlamp pumped Nd:YAG laser, with the insertion of solid state passive elements, can be made a source of trains of high power picosecond pulses with accurate pulse to pulse reproducibility. The combination of passive negative feedback using GaAs together with semiconductor quantum well saturable absorber in an actively mode-locked Nd:YAG laser led to generation of stretched 200 ns long trains with pulsewidth of 42 ps. Cavity dumping resulted in single pulses at energies of 500 (mu) J with a nearly Gaussian spatial profile at repetition rate of 5 Hz. Without passive negative feedback, stable 75 ns long trains of pulses with pulsewidth of 52 ps were generated.
