摘要

A folded four-mirror cavity with a composite Nd:YAG rod is optimized to obtain high efficient cw 473nm blue output. The laser could operate stably in the region of the thermal-lens focal length from 20mm to 70 ram. LBO is used for intracavity frequency doubling of the 946nm transition of Nd:YAG and the optimum LBO length is investigated. A maximum output power of 2.1 W in the blue spectral range at 473 nm is achieved with 30-mm-long LBO, corresponding to an optical conversion efficiency of 9.1%.
