What are Quantum Cascade Lasers (QCLs)?

Quantum Cascade Lasers (QCLs) are a class of semiconductor lasers that operate by exploiting electron transitions between quantum states in a series of quantum wells. Unlike traditional diode lasers, which emit light via bandgap transitions, QCLs utilize intersubband transitions, enabling them to emit light at mid- to far-infrared wavelengths. QCLs are renowned for their high efficiency, tunability, and ability to produce coherent light in regions of the electromagnetic spectrum that were previously difficult to achieve with traditional lasers.

Due to these advantages, QCLs have become the technology of choice in numerous cutting-edge applications, such as spectroscopy, gas sensing, medical diagnostics, and defense systems.
