This article discusses the high-power pumping conditions, how to effectively control the solid-state laser crystal temperature. At present, it is to explore a new type of cooling body - micro-channel heat sink in theory. this article will be applied to the theory of micro-channel cooling laser crystal for high-power pump laser cooling requirements.Besides, considerring the shape of solid-state laser crystals cylindrical design, a solid-state laser cooling of the micro-channel structure - cascading decline of fan spray cooling channel solid-state lasers. In this experiment the structure under the conditions of the internal crystal spatial distribution of the pump light in the pump source according to Gaussian distribution, pump power 10w, crystal with Nd: YAG, crystal, and this article designed by lateral micro-channel heat sink close to, and assume that all points of contact lens inside the outside temperature and the heat sink temperature equal to the whole surface of non-uniform to carry out a of. For the end-pumped lasers, the pump source heat through the side in order to improve the beam quality, take a smaller radius, which resulted in a small area to conduct heat consumption of heat, it is necessary for high-heat density problem analysis. In this structure, the crystal surface area of the smaller, then also means that micro-channel heat sink contact surface is very small, in a small contact surface of the micro-channels to achieve effective cooling is a technical problem, this section presents the following structure, which can effectively achieve the small thermal area of micro-channel structure, this paper presents a small area of heat dissipation structure. This process can be avoided dueing to the crystal due to high temperature welding caused by crack problems. The role of micro-channel heat sink is the ability to take away most of the crystal about the heat. Theoretical analysis proves that the device can achieve an effective heat dissipation, but also reduced the technique is very difficult to improve on the efficiency of temperature control of laser crystal. ·ÒëµÄ²»ºÃ£¬»¹Íû¼ûÁ |
