摘要：

Nonlinear optical conversion of 1.064 mu m pulses from a Q-switched Nd:YAG laser to the mid-infrared is demonstrated experimentally. The setup is based on a two-stage master-oscillator / power-amplifier (MOPA) design with a KTiOPO4 based MOPA in the fist state and a KTiOAsO4/ZnGeP2 based MOPA in the second stage. We obtain more than 8 m.J at 8 mu m with a beam quality factor M-2 approximate to 3.6.
