A two-photon pumped high-power cesium vapor blue laser generation system

Abstract

The application discloses a two-photon pumped high-power cesium vapor blue laser generation system and relates to the field of laser generation. First and second laser beam units modulate first and second pump modulation laser beams emitted by a laser beam generation unit, and the frequency, angle and power of the first and second pump modulation laser beams are freely changed, so that the intensity of the emitted coherent blue laser beam is improved. Compared with the prior art which improves the vapor chamber temperature to improve the coherent blue light power, the coherent blue light generation unit arranged in the application can modulate the intensity of the laser beam, so that the intensity of the laser beam is freely improved, and when the temperature of the vapor chamber reaches a threshold value, the coherent blue light power can still be improved by improving the intensity of the laser beam. The application proves the dependence of the coherent blue light power on the intensity of the laser beam, and simultaneously solves the problem that the coherent blue light power is limited by the vapor temperature.
