Abstract
We describe an external-cavity quantum cascade laser with an intra-cavity out-coupling optical system, tunable from 8.4 μm to 10.8 μm. The new optical configuration allows higher output power compared to a conventional Littrow-type external cavity approach, while keeping the broad tunability of wavelength. We achieved 1 W output power at the maximum in pulse-mode operation, which is more than twice the optical power using the Littrow design with the same gain chip.
摘要
我们描述了一种具有腔内出光光学系统的外腔量子级联激光器，可调谐范围从 8.4μm 到 10.8μm。与传统的里特罗型外腔方法相比，新的光学配置允许更高的输出功率，同时保持波长的宽调谐性。我们在脉冲模式下实现了 1W 的最大功率输出，这比使用相同增益芯片的里特罗设计的光功率高出两倍多。
