Application of the solid solution Cd_xHg_1–xGa₂S₄ as a nonlinear optical crystal

Abstract

We review the optical properties of the mixed crystal ${\mathrm{Cd}}_x{\mathrm{Hg}}_{1-x}{\mathrm{Ga}}_2{\mathrm{S}}_4$, propose three potential applications to which various physical properties can be tailored, and present experimental results of femtosecond optical parametric amplification in the mid IR from 5.5 to $8 \mathit{\mu }\mathrm{m}$ with $1.25‐\mathit{\mu }\mathrm{m}$ pumping by a 1-kHz Cr:forsterite regenerative amplifier.
