Abstract
Passively Q-switched neodymium lasers, Nd:YAG, Nd:YALO, and Nd:BEL, at 1.3 mum using the saturable absorber Co:ZnS were characterized. The best perfor mance, about similar to0.35 mJ pulse energy and 300 ns pulse duration, was obtained using the Nd:BEL laser. In a Co:ZnS Q-switched Nd:YAG laser, seque ntial dual-wavelength Q-switched pulses at 1319 and 1338 nm were observed. The time separation between the output pulses was about 2-10 mus. Theoretic al analysis is presented including analysis of the dual-mode Q-switched las er operation. (C) 2001 American Institute of Physics.
