Abstract

The invention relates to a multistage light condensing system which mainly comprises a third-stage reflecting mirror (2), a first-stage YAG crystal (3), second-stage reflecting mirrors (4), paraboloid mirrors (5), a second YAG crystal (6) and a third-stage reflecting mirror (7) of a semi-cylindrical mirror, wherein two sets of the second-stage reflecting mirrors (4) and the paraboloid mirrors (5) are arranged, the third-stage reflecting mirror (2) and the first-stage YAG crystal (3) are arranged on the first set, and the second YAG crystal (6) and the third-stage reflecting mirror (7) of the semi-cylindrical mirror are arranged on the second set. The multistage light condensing system has the higher sunlight-laser conversion rate and the higher pump light reflectivity, loss is small, the pump size is small, and the use effect is good.

Description

technical field [0001] The present invention relates to one, in particular to one, and belongs to the field of infrared spectroscopy equipment. Background technique [0002] Solar energy is a clean energy, but also an endless energy. All the energy sources on earth come from solar energy. Laser has excellent characteristics such as good monochromaticity, coherence and high energy density. Since its birth, laser has been rapidly applied in human society and greatly promoted the development of human society. At present, the pump energy source of laser is mainly electric energy, chemical energy, etc., but the application of solar energy as the energy source of laser is still in the research stage of the laboratory, and has not been put into practical application. However, looking forward to the prospect of directly pumping lasers with sunlight, we can see that it has great application value. People's research on solar-pumped lasers focuses on the following two aspects: one i...
