在高功率半导体激光器中，输入冷却水温度对输出功率和输出光谱都有影响。在双面泵浦板条激光器中，为了提高效率，必须对两个激光二极管阵列(LDA)的光谱进行优化。两个激光二极管的光谱失配会导致储能性能下降。本文研究了高功率激光二极管与激光介质的光谱重叠引起的热致效率下降。建立了描述LDAs冷却水温度和结构(串/并联)变化时蓄能变化的数值模型。利用双面泵浦平板组件进行了验证性实验。实验结果与仿真结果吻合较好。
In high power diode lasers, the input cooling water temperature would affect both output power and output spectrum. In double face pumped slab laser, the spectrum of two laser diode arrays (LDAs) must be optimized for efficiency reason. The spectrum mismatch of two LDAs would result in energy storing decline. In this work, thermal induced efficiency decline due to spectral overlap between high power LDAs and laser medium was investigated. A numerical model was developed to describe the energy storing variation with changing LDAs cooling water temperature and configuration (series/parallel connected). A confirmatory experiment was conducted using a double face pumped slab module. The experiment results show good agreements with simulations.
