Abstract

The invention discloses a high-power high-energy yellow-light Raman laser system, which comprises a pumping laser source, a laser coupling subsystem, a resonant cavity, a laser gain medium, an acousto-optic Q switch and a nonlinear frequency doubling crystal. The laser gain medium, the acousto-optic Q switch and the nonlinear frequency doubling crystal are sequentially arranged in the resonant cavity. The laser coupling subsystem comprises a first coupling lens and a second coupling lens, and the first coupling lens is located between the pumping laser source and the second coupling lens. Theresonant cavity comprises a first fundamental frequency light-Stokes light high-reflectivity mirror and a second fundamental frequency light-Stokes light high-reflectivity mirror, and the first fundamental frequency light-Stokes light high-reflectivity mirror is located between the second coupling lens and the second fundamental frequency light-Stokes light high-reflectivity mirror. The laser gainmedium comprises a first Nd:YAG crystal and a Nd:YVO4 crystal. The problems that an existing yellow light Raman laser cannot efficiently operate at high repetition frequency and low repetition frequency at the same time, and yellow light cannot be output at high power and high energy at the same time are solved.

Description

technical field [0001] The present application relates to the technical field of lasers, in particular to a high-power and high-energy yellow Raman laser system. Background technique [0002] The yellow laser with a wavelength in the range of 550-620nm plays an important or even irreplaceable role in many fields such as stimulated emission depletion fluorescence microscopy, laser sodium guide star, isotope separation and so on. However, the traditional method of preparing yellow-band lasers usually has a complex system structure and high cost, which is not suitable for mass production and has a small application range. Therefore, new ways to generate laser light in the yellow band are urgently needed. Yellow Raman lasers based on stimulated Raman scattering are a new way to prepare yellow-band lasers that has emerged in recent years. This type of laser has the advantages of simple and compact structure, high efficiency and good beam quality. [0003] However, the current ...
