Description

Brolis produces high power ( 100 mW+) single mode Fabry-Perot laser diodes in the region of 1.8 to 3.0 μm on GaSb. The Company has designed the first ever bent-waveguide gain chip based on GaSb, offering ultra-low <0.00005 reflectivity on the front facet and delivers unmatched gain performance. We package such gain chip with a TEC and current driver and then set the angle of a grating to lase at any wavelength over the 100nm+ range of each gain chip. This then gives single-mode performance and can be set to match an exact molecular absorption line.  The compact housing and high efficiency of  direct diodes enable simple integration into field deployable instruments. This is our brand new tunable infrared laser.

SensAline is a new tunable infrared laser product group featuring a high-performance Brolis mid-infrared gain chip for molecular spectroscopy, gas sensing and seeding applications. SensAline features our high-performance GaSb type-I gain chip embedded in Littrow cavity for single-mode tunable output. The laser offers over 12 nm of overall tuning around selected wavelength and has an integrated piezo for fine-tuning applications.

SensAline tunable infrared laser received the Innovation Award 2016 at CSindustry awards ceremony.
