Quantum cascade laser (QCL) critical component for standoff detection of chemical warfare agents

QCl

The quantum cascade laser is a special kind of semiconductor laser, usually emitting mid-infrared light. Such a laser operates on laser transitions not between different electronic bands but on intersubband transitions of a semiconductor structure. Applications include detecting chemical warfare agents and toxic industrial chemicals, monitoring building air quality, measuring …
