摘　　要：研究了 10 6 4nm红外激光通过具有LBO二阶非线性晶体的法 珀谐振腔的级联二阶非线性。研究结果表明 ,由于法 珀谐振腔的光反馈作用提高了谐振波长在LBO晶体内的功率密度 ,当 30 0mW的 10 6 4nm连续光入射时 ,仍可观察到级联二阶非线性现象。The transmission of 1064nm infrared pass through F P cavity, which has LBO second order nonlinear crystal inside was researched. The results show that the power density is increased obviously in LBO due to resonance of cavity. The cascaded second order nonlinear phenomena still can be observed in non single longitudinal mode continue wave 1064 nm beam with the input of 300 mW.
