我们演示了光泵浦量子点半导体圆盘激光器的多瓦连续波输出功率。在中心波长1032 nm处，连续波输出功率为4.35 W，斜率效率为22%。与之前发表的使用Stranski-Krastanow生长的量子点的结果相比，这意味着功率增加了15倍，斜率效率增加了10倍。采用内腔金刚石散热片进行热管理。最大输出功率受到可用泵功率的限制，没有观察到热翻转的迹象。(C) 2009年美国光学学会
We demonstrate multiwatt cw output power from an optically pumped quantum-dot semiconductor disk laser. Continuous-wave output power of 4.35 W with 22% slope efficiency was demonstrated at a center wavelength of 1032 nm. This represents an increase in power of 15 times and an increase in slope efficiency of 10 times from the previously published results using Stranski-Krastanow grown quantum dots. An intracavity diamond heat spreader was used for thermal management. The maximum output power was limited by the available pump power, and no sign of thermal rollover was observed.
