摘要：

We investigated the operation of a diode-pumped Yb:YAG laser passively Q-switched. by Cr4+:YAG, Cr4+:LuAG, and Cr4+:GSGG saturable absorbers. The results presented here are focused towards the design of a passively Q-switclied Yb:YAG microlaser. The free-running performance of both rod and a disk Yb:YAG is characterized and experimental parameters such as gain and loss are evaluated. These values. together with the value of the stimulated emission cross section. e.g. sigma(em)=3.3x10(-20) cm(2) were found to fit between our experimental results and an existing numerical model which relates the experimental and physical parameters to the minimal threshold pumping power. Q-switched pulses with maximum peak power of approximate to10.4-kW. and energy of approximate to0.5 mJ/pulse were extracted with 30 % extraction efficiency.
