摘要
利用周期谐振增益结构设计了以InGaAs/GaAsP/AlGaAs为有源区的980nm二极管泵浦垂直外腔面发射半导体激光器。根据理论模型计算了纵模限制因子、阈值增益、光增益、输出功率等特征参数,优化了激光器特征参数并设计了OPS VECSEL结构。理论计算表明,LD泵浦的垂直外腔面发射激光器的输出功率可大于1.0W。
By using period resonance gain structure, a laser diode (LD) pumped 980 nm vertical external-cavity surface-emitting laser (VECSEL) with active region of InGaAs/GaAsP/AlGaAs system was developed. The longitudinal confinement factor, threshold gain, optical gain and output power were calculated. The characteristic parameters of VECSEL were optimized, and the structure of VECSEL was designed. The results show that the output power of a LD-pumped VECSEL can be larger than 1.0 W based on the theoretical calculations.
