Paper Abstract

Orientation patterned GaAs and GaP crystals are increasingly being used for frequency conversion of laser beams into desired wavelengths. The ternary alloy InGaAs has smaller band gap energy compared to GaAs and is expected to have a nonlinear optical coefficient that is higher than that of GaAs. We will present the results of measurements of the second order nonlinear optical coefficient of InGaAs, along with recent measurements of GaAs and GaP obtained through second harmonic generation of a tunable carbon dioxide laser in the 9.2 to 10.6 μm range. The results will be compared to available values obtained at other wavelengths [1,2]

Keywords: nonlinear optics, frequency conversion, second harmonic generation
