Embodiment Construction

[0021] The principle of the high-power semiconductor double-end surface pumped second harmonic solid-state laser generation method of the present invention is as follows figure 1 As shown, the oscillator consists of a high-power fiber-coupled laser diode 1, a pump light converging system 2, an infrared total reflection mirror 3, a Q switch 4, an angle mirror (5, 7, 8), a laser crystal 6, and a green light output coupling mirror, double-frequency nonlinear crystal 9 and two-color total reflection mirror 10, wherein the angle mirrors (5, 7, 8) are small-angle mirrors in the cavity.

[0022] In order to reduce the inhomogeneity and damage of the laser medium absorption caused by the high-power laser diode single-ended laser crystal, in the present invention, two laser diodes 1 are used to pump simultaneously from the two end faces of the laser crystal 6 respectively, The pump light is uniformly distributed in the laser crystal 6 . According to the characteristics of different la...

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 demonstrated laser fineness, It is widely used in optical storage, underwater communication, precision measurement, laser medical processing and other fields. [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 laser technology, there is still a big ...
