20XX nm SAF gain-chip


Brolis 20XX nm single-angled-facet (SAF) gain-chip offers wide gain-bandwidth for most demanding spectroscopy applications such as CO2 sensing. Our 2 micron gain chip offers access to over 100 nm of spectral band. SAF gain-chip can be used as stand-alone broadband source – i.e. SLD for liquid solution sensing offering up to 40 mW CW output power or as gain medium with over 100 nm tuning around 2050 nm in external cavity configuration. In proper ECL setup our 2 micron gain chip can deliver up to 40 mW in single frequency with side mode suppression ration over 32 dB. Typical applications for the 2 micron gain chip include molecular specroscopy ( CO2, NH3, etc), LIDAR and seeding applications.

Note!  Current sotck items of 20XX nm SAF gain-chip are available only in C-mount package (see drawing). For more information, please contact us at info.
