Paper Abstract

We performed direct measurements of phase-matching conditions of Second-Harmonic Generation (SHG) and Difference-Frequency Generation using the sphere method to determine reliable Sellmeier’s equations valid in the 1-12 microns transparency range of the new BGSe monoclinic nonlinear crystal. We also recorded SHG conversion efficiencies under and out-of phase-matching conditions to determine without the magnitudes and relative signs of the associated non zero quadratic nonlinear coefficients of BGSe. By combining all these data, we were able to calculate pump wavelengths enabling the generation of a widely tunable light in the infrared range from phase-matched Optical Parametric Generation.
