Abstract

We report on the second harmonic generation of deep UV light in β-BaB2O4 (BBO) waveguides pumped by a frequency-doubled continuous-wave Nd:YAG laser. An output power of 0.32 mW at 266 nm has been achieved for an internal pump power of 670 m W. Optical channel waveguides in BBO crystals were produced by He+ ion implantation, lithographic masking and ion etching. The linear and nonlinear optical properties and the power handling capability of these waveguides are presented.
