摘要
Abstract
Ho :Sc2SiO5(Ho :SSO)crystal as a new saturable absorber was firstly exploited in the passively Q-switched operation of Tm:YAlO3 (Tm:YAP) laser .Under end pumping of 793 nm la-ser diode ,Ho:SSO passively Q-switched Tm:YAP laser can generate robust microsecond pulse output at 1 .88 μm wavelength .The 130 mW of average output power and 5 .2 μJ of pulse energy were obtained with the pulse duration of 1 .87 μs and repetition rate of 25 kHz .Further by incor-porating an acousto-optic (AO) modulator ,Ho:SSO-based hybrid Q-switched Tm:YAP laser was designed to compress pulse duration at hundreds of nanoseconds .The minimum pulse duration of 213 ns was achieved with the maximum pulse energy of 34 μJ at 4 kHz repetition rate .This work suggests an important application potential of Ho:SSO crystal as saturable absorber at 1 .9μm re-gion .关键词
