Repetition Operation of A 447.3 nm Blue–Violet Laser by Intracavity Frequency Doubling of an LD-Pumped Cesium Vapor Laser

Resumo

We investigate experimentally the repetition operation of a 447.3 nm blue–violet lasers pumped by intracavity frequency doubling of an LD-pumped cesium vapor laser. We study the output performance of the 447.3 nm laser using am LBO crystal as an intracavity frequency doubler. We obtain maximum power in the repetition operation of 0.36 mW, and the slope efficiency does not decrease in the range of pump powers from 2 to 16 W. Our results show that the thermal effect can be reduced in the repetition operation. The optimized working temperature of the LBO is ~25^°C, with a full width at half maximum (FWHM) of 4.1^°C.
