Nonlinear Optical Properties of KDP Crystal at Different Wavelengths
摘要
Abstract
The nonlinear optical properties of KDP crystal are tested at different wavelength by Z-scan technique.The KDP crystal exhibits reserve saturable absorption and self-focus effects under 355 nm and 532 nm wavelength with irradiation intensity of 57.92 GW/cm2and 105.94 GW/cm2respectively.The theoretical fitting values of nonlinear absorption and refractive are 6.50×10 -2cm/GW,1.17×10 -2cm/GW and 8.02 ×10 -7cm2/GW, 6.14 ×10 -7cm2/GW, while the KDP isn't detected any nonlinear optical properties at 1064 nm wavelength.The results show that KDP crystal has more obvious nonlinear optical properties in short wavelength and two-photon absorption is the main nonlinear absorption mechanism of KDP crystal.关键词
