| Abstract: | Based on the nonlinear interaction equations of light wave,this paper describes the second harmonic generation(SHG) together with an analysis of the relevant factors affecting nonlinear optical frequency conversion efficiency and classifies the conception of phase matching with an emphasis on the effect of taking quasiphasematching(QPM) technique to improve nonlinear optical frequency conversion efficiency.By comparing the birefringent phase matching(BPM) technique,we can clearly see the advantages of quasiphasematching technique in nonlinear optical process. |
