摘要

We have experimentally studied the passive Q-switching performance of a Nd: YAG ceramic laser with GaAs saturable absorber. Depending on the laser intensity in the GaAs wafer, the Q-switched laser showed much different performance. The shortest pulse obtained has 4.7 ns pulse width, 6.25 μJ pulse energy and 1.33 kW peak power.
