With a modelocked integrated external-cavity surface emitting laser (MIXSEL) we achieved a pulse duration of 144 fs. The MIXSEL belongs to the family of optically pumped semiconductor disk lasers. The MIXSEL operates at a center wavelength of 1033 nm with a 13-nm full width at half maximum optical bandwidth, at a pulse repetition rate of 2.73 GHz, and at an average output power of 30 mW. This new record result was obtained with an optimized multipair dielectric top-coating, a large bandgap material for strain compensation, a nonperiodic InGaAs quantum well gain structure, and an improved thermal management.
我们使用锁模集成外腔面发射激光器(MIXSEL)实现了 144fs 的脉冲持续时间。MIXSEL 属于光泵浦半导体盘激光器家族。MIXSEL 在中心波长为 1033nm 处工作,具有 13nm 的半最大值全宽光学带宽,脉冲重复率为 2.73GHz,平均输出功率为 30mW。通过优化的多对介电顶层涂层、用于应变补偿的大带隙材料、非周期性 InGaAs 量子阱增益结构以及改进的热管理,获得了这一新的记录结果。
