Abstract

CdGeAs2 has been found to be phase-matchable for type-2 SHG down to 2.833 μ m and type-2(b) SFG between the fundamental and second harmonic of a CO2 laser down to 10.4406 μ m at 20.0°C. The Sellmeier's equations and the thermo-optic dispersion formula which reproduce well the phasematching properties of SHG and direct FHG of the CO2 lasers at 77K are presented together with the absolute value of the nonlinear optical constant.
