The world’s smallest wavelength-swept quantum cascade laser (QCL), mountable in small spaces as a light source designed for portable volcanic gas monitoring systems
20 August 2021
By leveraging our unique micro-electro-mechanical system (MEMS) technology and optical mounting technology, Hamamatsu Photonics have newly designed and developed the world’s smallest wavelength-swept quantum cascade laser (QCL) to a size that is a mere 1/150th that of previous products!
This project also aims to increase analyzer sensitivity for detecting sulfur dioxide (SO2) and hydrogen sulfide (H2S) as well as simplifying maintenance. Doing so, will allow its use in applications for stable long-term monitoring of volcanic gas components near the craters of volcanoes. Other promising applications include detecting toxic gas leaks in chemical plants and sewers as well as making atmospheric measurements.
