Abstract

The invention relates to a multi-path tail end pump narrow pulse-width slice solid laser which comprises a first full reflection mirror (1), a dichroic mirror I (2), a crystal slice (3), a dichroic mirror II (4), a dichroic mirror III (5), a dichroic mirror IV (6) and an output mirror (7). Pulse-width compression is performed on a first pump light by a first pulse-width compression device (12), pulse-width compression is performed on a second pump light by a second pulse-width compression device (14), pulse-width compression is performed on a third pump light by a third pulse-width compressiondevice (13), pulse-width compression is performed on a fourth pump light by a fourth pulse-width compression device (15), then pulse-width compression is performed on an oscillation light in a resonant cavity by a fifth pulse-width compression device (8) and performed on the oscillation light outside the resonant cavity by a sixth pulse-width compression device (9), the oscillation light is injected into an oscilloscope (10), a computer forms control signals, so that pulse width is automatically adjusted, and picometer-level pulse-width laser output is achieved.

Description

technical field [0001] The invention relates to a solid-state laser generating device, in particular to a multi-channel terminal-pumped thin-chip solid-state laser with narrow pulse width. 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 smoo...
