中文摘要：
设计了一种新型的980nm底发射光抽运垂直外腔面半导体激光器（OPS-VECSEL），对比分析计算了器件在单个谐振周期内不同量子阱数目下的性能。得到了在单阱条件下，闽值光功率密度为5kW／cm。时，输出功率超过1．8W，斜率效率超过40％的优异性能。
英文摘要：
A new type of 980 nm bottom-emitting optically pumped vertical external cavity surface-emitting laser （OPS-VECSEL） is designed and the performance of the device in one optical resonance period with different quantum well numbers is analyzed. For single quantum well in one optical resonance period, the threshold power density of incident light is 5 kW/cm^2 , and the output power is higher than 1.8 W with a slope efficiency exceeding 40%.
