UV Solid State Waveguide Lasers

Aim: Realization of compact CW UV laser sources based on the frequency doubling in optical waveguides. Approach: Ridge-type optical waveguides in β-BaB2O4 are fabricated by He+ implantation, photolithographic masking and ion sputtering, or femtosecond laser ablation Impact: Compact CW UV lasers with a power of few mW will find applications in spectroscopy, microlithography, and data storage
