Abstract

Hg_0.35Cd_0.65Ga₂S₄ and Hg_0.52Cd_0.48Ga₂S₄ have been found to be phase-matchable for type-1 second-harmonic generation (SHG) of the fundamental radiation at 2.907-5.453 μm and 2.423-6.725 μm, respectively. The Sellmeier equations for HgGa₂S₄ and CdGa₂S₄ that reproduce well these experimental results as well as the published data for the Cr:forsterite laser (1.25 μm)-pumped Hg_0.35Cd_0.65Ga₂S₄ optical parametric generator (OPG) and the Ti:Al₂O₃ laser (0.820 μm)-pumped Hg_0.52Cd_0.48Ga₂S₄ optical parametric amplifier (OPA) at 5.59-9.12 μm are presented.
