Short Wave Infrared Laser 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. Based on InP technology, Alpes SWIR Laser Diodes emission can be tailored in the range from 1.45-2.2 microns with each design having a bandwidth of ~20 nm. Available wavelengths include the absorption bands of N2O, H2O, CH4 and HCl among others.
