Abstract :
Single Q-switched pulses have been generated in YSGG:Cr:Er with a 360-ns-risetime LiNbO3 electrooptical modulator. It is shown that birefringence losses can be avoided and spiking emission eliminated by placing an additional polarizing LiNbO 3 prism inside the laser resonator. Reproducible single Q -switched pulses of 200-ns duration have been generated
