According to the subnanosecond green laser provided by the invention, the output green laser has the characteristics of high repetition frequency, high average power and high monopulse energy, and can meet market application requirements.

Description

Technical field [0001] The present invention relates to the field of laser light, in particular, to a nanac green light laser. Background technique [0002] The Nanakocond green laser has a short output wavelength, high processing accuracy, has a broad application scenario in the field of laser microcompression, laser medical, nonlinear optics. [0003] The traditional full solid nana-second green laser is low, and it is not applicable to market applications. There is also a full-optical gas in the market, but its single pulse energy is small, and there is no cutting efficiency and cost advantage. Therefore, how to achieve high repetition frequencies, high average power, high single pulse energy, becoming a problem that needs to be solved. Inventive content [0004] It is an object of the present invention to provide a Nanaconcular green laser to solve the technical problems of the prior art high, high average power, high average power, high average pulse energy. [0005] The ob...
