Embodiment Construction

[0021] The basic composition and working principle of the present invention are described in detail below in conjunction with accompanying drawing and embodiment:

[0022] Such as figure 1 As shown, the specific implementation of this embodiment is as follows:

[0023] The gain pool includes upper and lower brackets, upper bracket 1 and lower bracket 2, each bracket includes three fluid flow channels, the two ends of the fluid flow channels are respectively inlet and outlet parts, and the inlet of the fluid flow channel 5 presents a width that slowly changes to Narrow shape, the outlet presents a shape that gradually widens from narrow, where the widest part of each fluid channel is 8mm, and the narrowest part is 0.3mm wide. The flow direction of each fluid flow channel is different, the flow direction of the two adjacent fluid flow channels is opposite, the flow direction of the first and third fluid flow channels of the three adjacent fluid flow channels is the upper bracke...

Abstract

The invention relates to the technical field of novel lasers, more specifically, a novel diode-pumping immersion-type liquid-cooling solid laser gain pool. The gain pool can solve problems that an immersion-type liquid-cooling solid laser is difficult in uniform heat dissipation, and poor in light beam quality. The gain pool consists of an upper support (1), a lower support (2), a quartz window (3), a gain medium (4), and two end cover plates. The gain pool ingeniously employs a technical route of single-cavity oscillation, and prolongs an optical path while guaranteeing the compact structure of a laser. The gain pool achieves the uniform cooling of two surfaces of the gain medium (4) through the laminar flow of high-pass liquid, ingeniously builds the technology of heat management, and improves the light beam quality of the laser.

Description

technical field [0001] The invention relates to the technical field of new lasers, and more specifically relates to a new diode-pumped immersion liquid-cooled solid-state laser gain pool, which can solve the problems of uniform heat dissipation and poor beam quality of the immersion liquid-cooled solid-state laser. Background technique [0002] Laser diode-pumped solid-state laser (DPL) is a laser that uses a laser diode as a pump source and a solid material such as a doped crystal as a gain medium. It has the advantages of compact structure, high electro-optical conversion efficiency and high reliability, and has become one of the main directions of current laser technology development. [0003] However, traditional diode-pumped solid-state lasers also have their own problems, among which poor thermal management technology has always been the key point restricting the development of solid-state lasers. In order to break through the bottleneck of thermal management technolo...
