Abstract

The invention discloses a laser capable of simultaneously outputting 1-micron waveband laser and 2-micron waveband laser, which comprises a laser pumping source, an input mirror, a composite laser medium and an output mirror, wherein the input mirror and the output mirror form a laser resonant cavity, the composite laser medium is placed in the resonant cavity, and the laser pumping source is placed in front of the input mirror. By optimizing the length of the composite laser medium, what is guaranteed is that the composite laser medium has enough absorption on laser pump light, the composite laser medium generates two kinds of light with different wavelengths under excitation of the pumping light, repeated refraction in a resonant cavity is enhanced, and simultaneous output of lasers with the wave bands of 1-micron and 2-micron is achieved.

Description

technical field [0001] The invention relates to the technical field of solid-state lasers, in particular to a laser capable of simultaneous output of 1 μm and 2 μm band lasers. Background technique [0002] Solid-state lasers in the 1μm and 2μm bands have their own characteristics and application fields. 1μm lasers have been widely used in marking, cutting, welding and other fields. However, transparent plastics have little absorption of 1μm-band lasers. Add some additives to improve the absorption of 1μm laser. The 1μm band laser can be transmitted by silica fiber, and has many important applications in medical treatment. However, due to the small absorption coefficient of water on the 1μm band, in some surgical operations, the penetration depth of the 1μm laser is deeper and the damage area is larger. Not very accurate. The 2μm band laser is located in the atmospheric window, the strong absorption band of water and the safe zone of human eyes. It has important applicatio...
