摘要

We present passively Q-switched microchip lasers with items bonded by spin-on-glass glue. PassiveQ-switching is obtained by a semiconductor saturable absorber mirror. The laser medium is a Nd:YVO_(4) crystal. These lasers generate pulse peak powers up to 20 kW at a pulse duration as short as 50 ps and pulse repetition rates of 166 kHz. At 1064 nm, a linear polarized transversal and longitudinal single-mode beam is emitted. To the best of our knowledge, these are the shortest pulses in the 1 (mu)J energy range ever obtained with passively Q-switched microchip lasers. The quasi-monolithic setup ensures stable and reliable performance.
