Abstract

In this paper, a laser diode with a center wavelength of 444nm is used as the pump source. Based on the pre-laser mode selection technology, combined with the F-P etalon technology for auxiliary mode selection, a single-longitudinal-mode pulse laser with a center wavelength of 639.7nm is developed. In the experiment, a stable single-longitudinal-mode laser output under high energy injection is realized by optimizing the parameters of the laser insertion element. When the output power of the pump source is 10.8W and the repetition rate is 20kHz, the maximum single-longitudinal-mode output pulse energy is 10.25μJ, the peak power is 170W, and the pulse width is 77.66ns.
