About Quantum Cascade Lasers

Quantum Cascade Lasers (QCLs) represent a fundamentally new class of semiconductor lasers that are capable of generating light in the mid- to longwave infrared portions of the spectrum, generally between 4 and 12 microns. Having no serious competition from other solid state light sources in this spectral window in wavelength agility, optical power, and size/weight, QCLs further existing applications and enable new ones in fields as diverse as spectroscopy, free space optical communications, and directed infrared countermeasures and other security areas. Today, Pranalytica is a vertically integrated QCL company, specializing in high power QCL devices and systems. For many applications, output power is the main figure of merit. To address this need, Pranalytica begins with its own patented as well as proprietary QCL designs that specifically target high power, high temperature operation. Our QCLs are fabricated in state-of-the-art facilities using the best available technologies. Pranalytica then applies its patented and proprietary packaging and thermal management solutions to fully extract the available device performance and to provide well-characterized and reliable products that can be easily integrated into real world systems. Pranalytica MonoLux is a wavelength tunable external grating cavity quantum cascade laser system consisting of one QCL.
