Quantum Cascade Lasers

 High-precision ethanol measurement using QCL


In this paper recently published by a collaboration between the EMPA Laboratory for Air Pollution and Environmental Technology and the Federal Institute of Metrology in Switzerland, a Quantum Cascade Laser manufactured by Alpes Laser was used for high-precision measurements of ethanol in breath-like air mixtures. Leveraging the intermittent CW method to cover a spectral range of 1.7 cm-1, the method achieved a measurement precision of 9 ppb while allowing cross-sensitivity measurement with CO2 and water, important parameters to ensure the validity of the method for law enforcement.

Short Wave Infrared Laser Diodes

Alpes Lasers introduces new Short Wave Infrared Laser Diodes. These diodes are continuous wave, multiple longitudinal mode Fabry-Perot devices emitting light over a bandwidth of ~20 nm with output power up to 50 mW. They are offered either as chip-on-carrier or encapsulated in a low power TO-66 package with collimated or divergent free-space beam output.
