激光二极管(LD)中心波长及LD功率影响着LD泵浦的固体激光器输出特性,通过理论和实验研究了LD的工作温度变化对LD中心波长及LD功率的影响,分析了LD温度控制系统的温控精度,给出了理论上确定温控精度的一般方法。实验结果验证了此方法的有效性,并且给出了以4 nm谱宽LD泵浦Nd:YAG时的温控精度数据。通过适当选择LD温控精度和较宽的LD谱宽,可大大降低温控系统设计的难度,有效提高DPL的环境适应能力。
The laser diode (LD) center wavelength and LD power affect the output characteristics of LD-pumped solid-state lasers. The effects of the working temperature of LD on the LD center wavelength and LD power are studied theoretically and experimentally. The effects of LD temperature control system temperature Control accuracy, given the theoretical method to determine the accuracy of temperature control. Experimental results verify the effectiveness of this method and give temperature-dependent accuracy data for Nd: YAG pumping at 4 nm spectral width. By proper choice of LD temperature control accuracy and wide LD spectrum width, the difficulty of design of temperature control system can be greatly reduced, and the environmental adaptability of DPL can be effectively improved.
