Abstract

The invention discloses a heat dissipating device for packaging of a high-power semiconductor laser device. The heat dissipating device comprises a bottom plate, a base, and a heat dissipation moduleof a single tube laser chip. A first-level cooling channel liquid inlet pipe and a first-level cooling channel liquid outlet pipe are arranged inside the bottom plate; a final liquid inlet is formed in one side wall of the bottom plate and is communicated with one end of the first-level cooling channel liquid inlet pipe; and a final liquid outlet is formed in the other side wall of the bottom plate and is communicated with the first-level cooling channel liquid outlet pipe. In addition, the invention also discloses a heat dissipating method for packaging of a high-power semiconductor laser device. The heat dissipating method comprises seven steps. According to the invention, a micro-channel heat dissipation structure is formed by three levels of channels; with the third-level micro-channelstructure, the good cooling effect of the high-power multi-single-tube laser device is ensured; and on the basis of the second-level micro channel and the first-level micro channel, a problem of a height difference between the heat dissipating modules is solved, so that processing of the inclination angle is avoided and the uniform heat dissipation is guaranteed.

Description

technical field [0001] The invention relates to the technical field related to semiconductor lasers, in particular to a heat dissipation device and method for packaging high-power semiconductor lasers. Background technique [0002] High-power lasers have a wide range of applications in the fields of industry and national defense. Compared with traditional lamp-pumped lasers, semiconductor lasers have many advantages such as small size, high efficiency, light weight, long life, and low cost, and play an increasingly important role in many aspects of the national economy. The multi-single tube combination of semiconductor lasers is the smallest optical module composed of single laser tubes, which can be directly combined to achieve fiber output. The advantages of multi-single-tube laser beam combining are: long life, high reliability, good slow-axis beam quality, and can be coupled into optical fibers with a core diameter of ≤100 μm; and the overall light source module is sma...
