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 μm. 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. AgGaSe2 and ZnGeP2 crystals were also investigated for comparison. |
