Quantum Cascade Laser (QCL) Technology

QCL technology is based on a principle called Tunable Diode Laser Absorption Spectroscopy (TDLAS), which measures the concentration of species in gaseous mixtures using tunable diode lasers and laser absorption spectrometry. Compared to other measurement techniques, such as paramagnetic detectors (“PMD”) and Chemi-luminescence, TDLAS offers multi-element detection capabilities, high accuracy with a wide dynamic range, low maintenance requirements, and a long life cycle. 

The use of lasers as spectroscopic light sources allows for high resolution spectroscopy (HRS), with QCLs offering access to the valuable mid infrared (MIR) part of the electromagnetic spectrum.
