Abstract

The invention discloses a 1064-nm intracavity pumping 2.3-micron thulium-doped solid laser. The 1064-nm intracavity pumping 2.3-micron thulium-doped solid laser comprises an input mirror, a 1064-nm laser medium, an intermediate mirror, a thulium-doped solid laser medium and an output mirror. The 1064-nm laser medium is utilized to generate 1064-nm laser, and the thulium-doped solid laser medium placed in the resonant cavity is pumped based on an up-conversion pumping mechanism to generate 2.3-micron waveband laser output. A 1064-nm laser resonant cavity is formed by reasonable coating, the input mirror and the output mirror, a 2.3-micron laser resonant cavity is formed by the intermediate mirror and the output mirror, a 1064-nm intracavity up-conversion pumping structure is formed, the characteristics of high intracavity laser power density and good light beam quality are fully utilized, and absorption of a thulium-doped solid laser medium to 1064-nm pumping laser can be improved.

Description

technical field [0001] The invention relates to the technical field of solid-state lasers, in particular to a 1064nm cavity-pumped 2.3μm thulium-doped solid-state laser. Background technique [0002] 2.3μm band corresponds to N 2 O(2.28μm), CO(2.36μm), CH 4 (2.37μm) and other important gas absorption peaks. N 2 O gas is one of the primary ozone-depleting substances emitted by humans, which can cause photochemical smog and is one of the main air pollutants. N 2 O is also a greenhouse gas, and CO 2 In contrast, although its content in the atmosphere is very low, its single-molecule warming trend is that of CO 2 298 times. CH 4 It is the main component of natural gas and is an explosive gas. Domestically, conventional 1.6μm semiconductor lasers are mainly used for its leak detection. CH 4 The absorption intensity in the 2.3μm band is about 3.5 times that of 1.6μm, so the use of 2.3μm lasers in leak detection will be easier to detect and more accurate. CO is a gaseous...
