Abstract

The invention relates to a secondary resonance solid laser generation of high-power semi-conductor dual-end pump. Wherein, it uses optical fiber to couple the laser diode dual-end pump single laser crystal; uses matrix optics to optimize design; uses foldable four-mirror chamber structure with non-focus lens to obtain the infrared laser with high-effect resonance conversion, large base module volume and small light waist diameter; uses non-linear program to design, selects non-critical phase match and right time-frequency crystal size, via time-frequency non-focus method and foldable plane chamber structure, to obtain dual accumulated high powers, high effect single-mode secondary resonance, to be output via angle mirror polarized.

Description

Technical field

[0001] The invention relates to a semiconductor end-face pumped second harmonic solid-state laser generation method. Background technique

[0002] With the rapid development of laser diodes (Laser Diode), LD pumping technology has been rapidly improved. In recent years, end-pumped lasers (especially end-pumped second-harmonic lasers) have rapidly become popular in laser demonstrations, laser fine-tuning lasers, etc. , optical storage, underwater communication, precision measurement, laser medical processing and other fields are widely used.

[0003] Current international sales of end-pumped Q-switched TEMs 00 SHG laser products, such as Evolution-TEM from Coherent Corporation 00 Nd:YLF 15W / 527nm / 5KHZ / 200ns green laser; the maximum average laser power of American Spectrophysics Corporation is 11W / / 50KHZ / 13ns TEM 00 HIPPOH10-532Q green laser; In China, due to the relatively weak system integration capability and achievement industrialization capability of ...
