基于亚带间跃迁的量子级联激光器（QCL）在室温下在中红外或“分子指纹”光谱区域（3.4{17 m）中工作，已被发现对包括环境传感、污染监测和医疗应用在内的几种应用很有用。在本教程中，我们介绍了中红外量子级联激光器的设计和发展及其应用。关键词：激光，子带间跃迁，量子级联，中红外，量子阱
Quantum cascade lasers (QCL) based on intersubband transitions operating at room temperature in the mid-infrared or `molecular ngerprint' spectral region (3.4{17 m) have been found useful for several applications including environmental sensing, pollution monitoring, and medical applications. In this tutorial review we present an introductory overview of the design and development of mid-infrared quantum cascade lasers and their applications. Keywords: laser, intersubband transitions, quantum cascade, mid-infrared, quantum well
