基于量子级联激光器的气体检测研究
Gas Detection Based on Quantum-cascade Lasers
摘要
随着社会的发展,对基于激光光谱技术的快速、灵敏和选择性气体探测的需求日益增加,量子级联(QC)激光器特有的高输出功率、宽调谐范围和能够在室温或者接近室温下工作的特性使它成为气体遥测的理想光源。详细描述了QC激光器,介绍了基于室温脉冲QC-DFB激光器的典型的中红外激光光谱实验装置,并探讨了QC激光器应用于气体检测的广阔前景。
Abstract
There is an increasing need in many fields for fast, sensitive, and selective gas detection based on laser spectroscopy with the development of society. Quantum-cascade lasers are ideal light sources with its special characteristics of power, tuning and capability of operating in or near room-temperature. Quantumcascade lasers and a typical mid-infrared laser spectrometer based on a room-temperature distributed-feedback pulsed QC laser are described in detail, and the bright future of QC lasers used in gas detection is also showed.
