Quasi-phase-matching(QPM) periodical poled LiNbO3 （PPLN） is designed and successfully fabricated to enable second harmonic generation (SHG),The samples were Z-cut 0.5 mm thick and grating period is A=6.8 μm for the first order QPM of contimual wave λ=1.064μm which is emitted by Nd:YAG laser at room temperature 27℃,The output single-pass SHG power was tested by an authorized optical system.The normalized max conversion efficiency is calculated to be 0.25% (W.cm)^-1,The fabrication and parameters calculated method are introduced,and testing scheme is described in this paper,Even some ideas to improve conversion efficiency are offered.  相似文献
