NIR Laser Product Portfolio with Higher Optical Power

Dec 16 2011

VERTILAS (Germany) announces that the product line of laser diodes for sensing applications has now been extended with lasers featuring higher optical power. These new VCSELs provide up to 100 % more in optical power compared with standard products. Initial wavelengths available are in the range of 1570 to 1600 nm and feature up to 5 mW in optical power.

Vertilas offers a comprehensive product range of VCSELs from 1.27 µm to over 2.3 µm for NIR gas analysis. All laser products are available in various packaging options, incl. TO-cans and fiber coupled optical sub-assemblies. These package types can be supplied with integrated thermo-electric cooler (TEC) and thermistor.

Vertilas laser products are based on its unique Buried Tunnel Junction (BTJ) Vertical Cavity Surface Emitting (VCSEL) technology. This technology allows a wider and faster tuning range than other available laser technologies. The circular beam shape of BTJ VCSELs enables an optimised optical system design. Furthermore, Vertilas’ high performance BTJ VCSEL diodes feature very low power dissipation, making them ideal for both high end as well as compact and battery operated sensing equipment.
