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
