摘要

We have investigated the generation of highly-efficient blue light in critically type-I phase-matched LiBsO5(LBO) with intracavity frequency doubling of diode-pumped Nd: YA G laser. A maximum output power of 502 m W at 473nm blue light was obtained and the overall optical-to-optical efficiency is up to 11.2%. To the best of our knowledge, this is the highest conversion efficiency for 473 nm output using a diode pumped Nd:YAG laser through LBO.
