Advances in quantum cascade lasers for critical real-world applications
Advances in quantum cascade lasers for critical real-world applications - A Frankfurt Laser Company and mirSense White Paper
Laser spectroscopy is a cornerstone technology in modern gas detection, enabling precise measurement of molecular concentrations in gases, liquids, and solids. By exploiting the fact that molecules absorb infrared (IR) light at specific wavelengths, spectroscopy can provide a non-invasive and accurate method of chemical analysis. However, successful implementation depends heavily on selecting the right wavelength for the target molecule.
mirSense’s uniMir distributed feedback (DFB) quantum cascade lasers (QCLs) uniquely address this challenge by offering emission in the 10-19 micron wavelength range. This is a groundbreaking capability, as these long wavelengths are not only highly selective for certain gases but also offer enhanced performance in pulsed operation due to reduced intrapulse linewidth broadening.
This White Paper explores recent advancements in quantum cascade lasers and their applications in fields such as environmental monitoring, industrial process control, and, critically, nuclear safety. It discusses the technology’s underlying principles, the benefits of long-wavelength detection, reveals the real-world applications, and highlights the advantages of mirSense's uniMir QCLs, specifically their operation in the 10-19 micron wavelength range.
