摘要

By optimising the resonator and choosing a periodically poled KTiOPO4 (PPKTP) crystal as the doubler, a tunable single-frequency 461 nm laser with good performance is achieved. The output power at 460.86 nm and beam quality are of 1.05 W and better than 1.1, respectively. 'The measured linewidth is less than 590 kHz for 50 ms. By scanning the optical length of the resonator, the continuous frequency-tuning range of 15.756 GHz for the 460.86 nm laser is obtained.
