Problems solved by technology

The introduction of an optical system with compressed beam divergence can allow the pump source not to be squeezed into a small space near the laser medium, but the structure is very complicated, which not only increases the cost, reduces the reliability, but also deteriorates the uniformity of the irradiation

Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment and accompanying drawing, but should not limit the protection scope of the present invention with this.

[0019] Please refer to Fig. 1 first, Fig. 1 is the structural cross-sectional view of the embodiment of the side-surrounding pump module used for the rod-shaped laser medium of the present invention, as can be seen from the figure, the side-surrounded pump module used for the rod-shaped laser medium of the present invention includes a The ring-shaped heat sink block of the cooling liquid microchannel and the bar 3 packaged on the ring-shaped heat sink block.

[0020] The annular heat sink plate is composed of a heat sink core 1 and a heat sink frame 2. The heat sink core 1 is an annular ring with a polygonal through hole in the central axis and an outer circle with a heat sink core opening 103. Block, the outer circumference of the heat sink core 1 is engraved with a plurality of co...

Abstract

This invention discloses a laterial circulating pumping module made of bar-type laser medium comprising quasi-micro-channel liquid-cooling heat-sink, and bar piece packaged on the same. The pumping light source being refrigerated by micro-channl is circulating the bar-type solid laser medium, evenly distributing and directly radiating. The advantages of this invention are: centralizing as high as possible pumping power, forming even pumping light-field, to realize quick cooling and constant temperature control, high efficient spectrum coupling between laser medium and the pumping light-field; easily to realize modularization, stacking-able, rotating, increasing pumping power several times over, obtaining more even gain from the bar.

Description

technical field [0001] The invention relates to lasers, especially a side-surround pumping module for rod-shaped laser media, especially suitable for gathering a large number of high-power laser diode linear arrays (commonly known as "bars") to uniformly side-pump solid-state laser media. Background technique [0002] How to gather a large number of high-power laser diode linear arrays (hereinafter referred to as "bars") and form a suitable light field distribution, how to achieve rapid cooling and constant temperature control of the pump light source to increase the total power of the pump light and maintain the spectrum Stability and uniform irradiation are the core issues of side pumping technology in high-power all-solid-state lasers. The size of the bar device is not small, and the diameter of the rod-shaped laser medium is limited, so it becomes a big problem to arrange many bars around it. The introduction of an optical system with compressed beam divergence allows t...
