Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] In the phase-change thermal control system of the present embodiment, the laser diode array is installed on the thermal control system. When the laser diode array works (the laser diode array works in intervals), each laser diode 1 performs electro-optical conversion, and a part of The energy is converted into heat energy, which is transmitted to the packaging shell of the laser diode 1. The purpose of the thermal control system is to dissipate the heat from the large number, high power, and densely distributed laser diode shells, so as to ensure the high reliability of the laser diode 1. , High electro-optical conversion efficiency work.

[0040] Simultaneously the applicant finds in practice, for the laser diode array of high power, sparse array, because heat can form " hot spot " (the position temperature of installing laser diode is...

Description

technical field [0001] The invention belongs to the technical field of lasers, and in particular relates to a phase-change thermal control system and method for a high-power laser diode pump source array. Background technique [0002] The main components of a laser are a resonator, a pump source and a working substance. The role of the pump source is to excite the laser working material and pump the activated particles from the ground state to a high energy level, so as to realize the inversion of the number of particles. Common pumping methods include electrical pumping, chemical pumping, optical pumping and pneumatic pumping, among which optical pumping and electrical pumping are the most widely used, and electrical pumping is often used in gas lasers as The optical pumping method is widely used as an excitation source in solid-state and liquid lasers. Optical pumping is to irradiate the working substance with a beam of light, so that the particles in the working substan...
