| Abstract: | AgGa1-xInxS2 with x=0.14±0.01 was found to be 90° phase-matchable for type-I difference-frequency generation (DFG) by mixing the dual-wavelength
pulses emitted from an electronically tuned Ti:sapphire laser. Infrared radiation continuously tunable over the range of 4.80–6.98 μm
was generated by independently varying the two wavelengths in the 705–932 nm spectral range, and 4.04 μm radiation by mixing
a Nd:YAG laser with the Ti:sapphire laser. In addition, this material was found to be noncritically phase-matchable for the
second harmonic generation (SHG) of CO2 laser radiation at 10.591 μm at 203 °C. Sellmeier equations that reproduce well these experimental data are presented.
