| 摘 要： | 给出了808 nm/980 nm双反射带布拉格反射镜的反射谱线,建立了光泵浦双反射带半导体激光器件的热学模型及其内部热载荷分布形式,运用有限元分析方法,详细分析了双反射带光泵浦半导体激光器件的热学特性。结果表明,对于激射光反射率为99.96%的单反射带和双反射带布拉格反射镜结构的垂直外腔面发射半导体激光器件,前者的散热性能较好,而后者的最大温升明显低于前者。本文的分析结果可为半导体激光器件的结构优化和实验研究提供理论参考。

| Abstract: | The reflectivity spectra of 808 nm/980 nm double band mirror(DBM) are characterized in the paper.According to the structure of the DBM,the thermal model of Optically Pumped Vertical-External-Cavity Surface Emitting Semiconductor Lasers(OPS-VECSELs) with DBM is constructed and the distribution of thermal load in the VECSEL wafer is presented.The thermal characterization of OPS-VECSELs with DBM is analyzed in detail by finite element method.The results indicate that VECSEL wafer with DBM has better thermal properties and poorer thermal performance than with DBM when they have the same reflectivity(R=99.96%).So VECSEL wafer with DBM is more suitable for making high power semiconductor laser than with DBM.The theoretical analysis results will be provided as theory reference for VECSEL wafer structure optimization and experimental. |
