摘要：

The optical properties of a new promising nonlinear mixed AgGaxIn1-xSe2 crystal were investigated. Its absorption coefficients and refractive indices were determined at wavelengths 0.8 - 19 mu m. For the first time the coefficients of the Sellmeier dispersion equations were determined for different indium contents. The corresponding phase-matching diagrams for second-harmonic generation and an optical parametric oscillator pumped by a Er3+:YAG laser were calculated and plotted. An experiment on the generation of the second harmonic of a TEA CO2 laser and a Q-switched laser was carried out and a frequency doubling efficiency of 10.9% was obtained. AgCaSe2 and ZnGeP2 crystals were also investigated for comparison.
