Abstract

We demonstrate phase-matched difference frequency generation in the emerging nonlinear crystal La₃Ga_5.5Ta_0.5O₁₄. Tunable wavelengths between 1.4 and 4.7 μm are generated by using femtosecond sources. We also report on the measurements of the optical damage threshold in the femtosecond regime and on the nonlinear refractive index n₂.
