Abstract

The invention discloses a bicrystal high-power green light solid laser which comprises a first light path device and a second light path device arranged on one side of the first light path device. The first light path device and the second light path device are opposite in direction and are used in cooperation with each other. The device is reasonable in design, convenient to operate and high in working efficiency. The pump light which is not absorbed can be reflected back to the laser body through the lens combination by arranging the total reflective mirror, so that high and smooth absorption of the pump light is realized; therefore, the thermal load is dispersed to the whole crystal length, and the thermal load on the input end face is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a double-crystal high-power green solid-state laser. Background technique [0002] Continuously operating high-power, high-beam-quality green light laser. Large-scale argon-ion lasers were the first to deliver more than 30W of power with near-diffraction-limited beam quality, but because of their very low efficiency, they typically require tens of kilowatts of power and large-flow water cooling cycles. In recent years, with the emergence of high-power laser diodes and high-quality neodymium-doped vanadate and nonlinear crystals, 532nm intracavity frequency-doubled lasers have been widely used commercially. In the case of beam quality close to the diffraction limit At first, a stable noise-free output power of 5-10W can be obtained. Although the output power has been increasing, its output power still cannot meet industrial requirements in commercial applications. Contents of ...
