Shortwave Infrared Diode

Short Wave Infrared Diode Lasers 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 Diode Lasers emission can be tailored in the range from 1.45-2.2 μm with each design having a bandwidth of ~20 nm. At this moment the following central wavelengths are available with a 8 weeks lead time:
