Abstract
The nonlinear optical properties of β-BaB204 (beta barium borate) are demonstrated in the generation of second through fifth harmonics of 1.06 μm neodymium laser radiation and in optical parametric oscillation pumped by 532-nm radiation. βBaB204 is particularly useful for high average power applications and nonlinear frequency generation in the ultraviolet to wavelengths as short as 200 nm. An internal energy conversion efficiency of 84% for 1064-nm to 532-nm second harmonic generation, and cascaded harmonic conversion to the 213-nm fifth harmonic with 11% overall conversion were obtained. The observed performance agrees well with that predicted by modeling.
