最近演示的外腔量子级联激光器与光反馈，由声光调制器控制，铺平了道路，以坚固的红外激光系统的发射波长调谐在微秒级的能力。这种系统对于需要超快速波长调谐的各种关键应用（包括燃烧和爆炸诊断以及间隔检测）非常重要。本文总结了近年来这类器件的研究成果，并结合实际应用分析了新结构的优点。
The recent demonstration of external cavity quantum cascade lasers with optical feedback, controlled by an acousto-optic modulator, paves the way to ruggedized infrared laser systems with the capability of tuning the emission wavelength on a microsecond scale. Such systems are of great importance for various critical applications requiring ultra-rapid wavelength tuning, including combustion and explosion diagnostics and standoff detection. In this paper, recent research results on these devices are summarized and the advantages of the new configuration are analyzed in the context of practical applications.
