Paper Abstract

This paper reports on the phase-matching properties of GaS0.4Se0.6 for type-2 difference-frequency generation (DFG) between a Nd:YAG laser and a Nd:YAG laser-pumped β-BaB2O4 optical parametric oscillator (BBO/OPO) in the 100.4- 1030.6μm (0.291-2.988THz) range together with the refined Sellmeier equations for GaSxSe1-x (x=0, 0.29, 0.40, and 1.0) that provide a good reproduction of the present experimental results as well as second-harmonic generation (SHG) to sixth-harmonic generation (6HG) of a CO2 laser at 10.5910μm and a Ti:Al2O3 laser-pumped THz generation in the 1~1.8THz range.
