DFB laser diodes from Nanoplus enable gas sensing

Jan. 5, 2012
Singlemode distributed-feedback (DFB) laser diodes in the 2.9–3.5 μm wavelength range enable gas sensing using tunable diode laser spectroscopy (TDLS), which detects gas species at trace levels in the parts-per-million (ppm) range.

Singlemode distributed-feedback (DFB) laser diodes in the 2.9–3.5 μm wavelength range enable gas sensing using tunable diode laser spectroscopy (TDLS), which detects gas species at trace levels in the parts-per-million (ppm) range. The laser diodes can detect different hydrocarbons, such as CH4, C2H2, C2H6, and C3H8, with increased sensitivity.

PRESS RELEASE

“A new class of laser sources with performance formerly unattainable has been developed in the wavelength range between 2.9 - 3.5 µm and is now made commercially available for TDLS applications.

Our innovative DFB laser sources will now enable a new qualitative level of monitoring techniques using TDLS. By using the fundamental transitions instead of presently used overtones, different hydrocarbons (like CH4, C2H2, C2H6, C3H8 and others) can be more easily distinguished and the sensitivity can be increased by several orders of magnitude. Some of these gases were not detectable by TDLS at all before. This also opens up entirely new fields of applications. If you want to learn more, please see: www.nanoplus.com/3500nm.”
