摘要

A single-frequency 397.5 nm laser by means of an intracavity frequency-doubled Ti:sapphire (Ti:S) laser is presented. In order to obtain the second-harmonic generation with low threshold pump power and high out power, the optimal length of the Ti: S crystal is theoretically analyzed and experimentally measured. The experimental results are in good agreement with the theoretical expectation by comparing the experimental result to the theoretical value of the threshold pump power. After inserting the nonlinear BIBO and LBO crystals, the obtained output powers of the 397.5 nm laser are 1.58 and 0.78 W, respectively. Lastly, the tuning characteristic, power stability, and beam quality are also discussed. (C) 2015 Optical Society of America
