The invention relates to a multi-path tail end pump thin sheet solid laser. The multi-path tail-end pump thin sheet solid laser comprises a first total reflecting mirror (1), a dichroic mirror I (2),a crystal thin sheet (3), a dichroic mirror II (4), a dichroic mirror III (5), a dichroic mirror IV (6) and an output mirror (7); a first pump light, a second pump light, a third pump light and a fourth pump light are all pump light formed by a 790nm semiconductor laser; the crystal thin sheet (3) is Tm: YLF crystal; the oscillation light is 1,908nm laser; the first total reflecting mirror (1) isplated with a 1,908nm high reflecting film; the dichroic mirror I (2), the dichroic mirror II (4), the dichroic mirror III (5) and the dichroic mirror IV (6) are plated with a 1,908nm high reflectingfilm and a 790nm high transmission film; the output mirror (7) is plated with a 1,908nm partial transmitting film; and all light transmission surfaces of the crystal thin sheet (3) are plated with high transmission films of 790nm and 1,908nm. By virtue of the laser, the beam quality of the thin sheet laser is improved and the laser output power is increased.
Description
technical field [0001] The invention relates to a solid-state laser generating device, in particular to a multi-channel end-pump thin slice solid-state laser. Background technique [0002] Solid-state lasers have important applications in the fields of biomedicine, spectroscopy, atmospheric detection, and photoelectric countermeasures. The thermal effect of laser crystals is a major obstacle to the improvement of laser performance. Flake-shaped laser crystals can effectively alleviate the negative impact of thermal effects due to their large heat dissipation area, and have won people's favor. Diode-pumped thin-sheet lasers are used in a wide variety of applications. In terms of material microprocessing, the output of LD-pumped thin-sheet lasers is stable and high-power, and the output laser beam quality is good. It is very popular in the material micro-processing industry. The holes are deeper than other types of lasers and the edges are smooth; LD-pumped sheet lasers hav...
