Abstract

Caliber mortar projectiles and bombs are now tend to use the laser fuze because of its high accuracy in distance measurement，the strong ability to resist electromagnetic interference, the high angular resolution and the good concealment. Otherwise, the microlaser can bring about some alluring benefits. For instance, it can generate high quality laser beam, which has small divergence angle and high power. So, This paper summarizes some key factors which have impacts on the output of LD-pumped passively Q-switched subnanosecond microlasers, including the initial transmission of the absorber, the reflection of output coupler, the length of the cavity and the radius of the pumping laser beam, and gives the conclusion of the simulation based on the variation of the density of the reversal particle in the resonant cavity derived from the oscillation equation of the LD-pumped passively Q-switched Cr4+:YAG/ Nd:YAG laser, which provides the basis for the design of the passive Q-switched micro lasers which have high power, high repetition frequency and narrow pulse width.
