不要翻译工具直接翻译的，若被采纳金币如数赠送，翻译的好的话另加110的辛苦费 本文讨论了有效控制二极管泵浦固体激光器晶体工作温度的方法。目前，从理论上探索了一种新型的散热体—微通道热沉。文中将微通道散热理论应用到激光器晶体上，针对二极管泵浦固体激光器散热的要求，并且考虑到二极管泵浦固体激光器晶体的形状为圆柱形，设计了一种固体激光器冷却器的微通道结构——串接扇形喷射式微通道固体激光器冷却结构。 该微通道的设计是在本文结构条件下、晶体内部空间分布、泵浦源的泵浦光按高斯分布、泵浦功率为10w、采用Nd:YAG晶体、晶体外侧由和本文设计的微通道热沉紧贴，并且假定在所有接触点晶体外侧温度和热沉内侧温度相等、整体表面上为非均匀等条件下进行的。对于端面泵浦激光器，泵浦源通过侧面进行散热。为了提高光束质量，可取较小的半径，但同时造成了要在小的面积进行高热耗散热。于是，就要进行高散热密度问题的研究。在此结构中，晶体表面积较小。那么也就意味着微通道热沉接触面很小。而在小接触面上实现有效的微通道散热是一个技术难题。本文提出了一个合适的结构——能有效实现小散热面积的微通道结构。 这种设计方案可以避免由于焊接使晶体因温度过高而导致崩裂的问题。同时，微通道热沉又能够带走激光晶体的大部分热量。理论分析证明该器件既实现了有效散热，又降低了工艺难度，提高了对激光晶体温度的控制效率。 [ Last edited by soitermen on 2010-1-20 at 21:49 ] |

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. 翻译的不好，还望见谅 |
