Abstract

We report on the synthesis and the measurement of the properties of large single crystals of a new synthetic nonlinear optical material of the sulfosalt type, Tl₃AsSe₃. The crystal space group is R3m; the refractive indices range from 3.14 to 3.44 with n₀ − n_e = 0.18 (negative uniaxial), and the material is transparent from 1.26 μm to beyond 17 μm. The nonlinear optical susceptibilities are of the order of three times those of Ag₃AsS₃ (proustite), in reasonable agreement with Miller’s rule, and the measured phase-match angle for frequency doubling of the CO₂ laser output (10.6 μm) is θ_m = 22 ± 2°. Calculations of tuning curves for parametric oscillation indicate the possibility of angle tuning over the entire transparency range of the crystal; pumping at 2.06 μm. (Ho³⁺-doped YAG or SOAP) appears to be a promising technique for obtaining efficient tunable parametric oscillation in the 3–5-μm region.
