前言:量子级联激光器(Quantum Cascade Laser,简称QCL)是一种新型半导体激光器。QCL拥有传统半导体激光器的体积小、寿命长等特点,但是其工作原理却和传统半导体激光器截然不同。传统半导体激光器发光机制是导带和价带中的电子空穴对复合发光,而QCL则是利用电子在导带子带间的跃迁发光,全程只有电子参与受激辐射。QCL是半导...

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. Figure 1 shows what happens to an electron injected ...
