Abstract

Some laser experimental parameters in infrared nonlinear optical crystal Na2 Ge2 Se5 were calculated, including the illustration of second-harmonic generation (SHG) phase matching curve in the principal planes, SHG phase matching curve with pump of 0.946 μm, 1.064 μm, 1.1319 μm and sum-frequency generation (SFG) phase matching curve of producing 0.589 μm 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.
