Setting the standard for QCL control technology

What is a quantum cascade Laser (QCL)?
QCLs are semiconductor lasers that emit in the mid- to far-infrared section of the electromagnetic spectrum. QCLs achieve their emissions differently from standard semiconductor lasers. A unique superlattice structure, repeated series of thin layers, gives electrons a varying potential across the device. This unipolar operation is known as a one-dimensional multiple quantum well confinement and it allows the band or possible energies to split into a number of discrete subbands. The energy level in the system is based on the thickness of the bands, not on the specific material, making it possible to fine-tune the emission wavelengths in the same QCL system over a wide range. This wide tuning range allows for rapid and precise detection of trace elements, especially useful for industrial exhaust sensing, safe-distance explosive detection, medical diagnostics, and a number of other sensing and spectroscopic applications.

CEMTEK KVB-Enertec QCL Emissions Analyzer
The most exciting and promising possibilities of QCL technology are in the areas of gas measurement and sensing. CKE is at the forefront of this technology. Our QCL systems can be used to measure diverse gases concentrations in the parts-per-trillion range. With advanced QCL technology, local and remoted sensing of CO, CO2, NH3, CH4, NOX, and SO2 is not only possible, but remarkably simple. QCL systems are small, rugged, and consume relatively little power, making them ideal for both lab and field work.
