Numerical Analysis of Infrared Nonlinear Optical Crystal Na2Ge2Se5 on the Nonlinear Frequency Conversion

Abstract

Abstract:

Some laser experimental parameters in infrared nonlinear optical crystal Na2Ge2Se5 were calculated, including the illustration of SHG phase matching curve in the principal planes, SHG phase matching curve with pump of 0.946μm, 1.064μm, 1.1319μm and SFG phase matching curve of producing 0.589μm laser. The results were also analysed so that they can provide useful theoretical references for optical design of infrared tunable and new wavelength laser devices.

Key words: nonlinear optics, phase matching, Na2Ge2Se5, second-harmonic, SFG
