It is the only manufacturer worldwide routinely providing single and multi mode lasers at any wavelength from 760 
to 6000 nm. At wavelengths up to 14 µm, QCLs complete BeamQ’ laser portfolio. Our patented distributed feedback laser diodes deliver single mode emission with well defined optical properties enabling a wide range of applications. BeamQ lasers operate reliably in tens of thousands of installations worldwide, including chemical andmetallurgical in dustries, gas pipelines, power plants, medical systems, airborne and satellite applications.

BeamQ lasers with excellent performance are specifically designed and characterized to fit your needs. This data sheet summarizes typical properties of BeamQ DFB lasers in the range from 1650 nm to 1850 nm range. In this wavelength range e.g. methane, nitric oxide and hydrogen chloride can be detected with high sensitivity. Overleaf data is given as an example for DFB lasers used for high sensitivity HCl sensing.


DFB laser diodes at 1742 nm
A wide variety of gas molecules exhibit characteristic absorption lines in the near infrared. DFB lasers emitting at 1742 nm are highly suited for sensitive detection of small HCl concentrations. For this application, highly stable laterally and longitudinally single mode lasers 
are required.This data sheet reports performance data of BeamQ DFB lasers at this wavelength. Similar 
performance data are obtained in the entire wavelength range from 1650 nm to 1850 nm. For examples of performance data of BeamQ lasers in other wavelength ranges.
