摘要：

针对半导体泵浦固体激光器(DPL)中激光晶体的温度分布问题,提出了一种在工作状态下对其进行实时监测的方法。该方法以基尔霍夫衍射原理为依据,通过对工作状态的激光器出射光斑进行实时检测,得到其光场分布,根据晶体折射率分布,对出射光斑光场分布的影响以及折射率变化与温度变化的关系,建立数学方程,推导并得到激光晶体内部的温度分布的解。该方法符合激光器实际工作情况。通过实例,验证该方法切实可行。

关键词: DPL, 激光晶体, 温度分布, 实时检测

Abstract:

Since the temperature in laser rods has a significant impact on laser performance,the realtime detection of temperature distribution in the laser is very important to a DPL.A method for detecting the temperature distribution in the laser rod is given in this paper.The temperature distribution can be obtained from the laser beam intensity detected by CCD using mathematical approaches and modeling realized by computer.Compared with conventional methods,the proposed method accords better to the real laser working condition.Its feasibility is verified by experiments.

Key words: DPL;laser rod;temperature distribution;realtime detection
