nanoplus lasers with excellent performance are specifically designed and characterized to fit
your needs. This data sheet summarizes typical properties of nanoplus DFB lasers in the 2900
nm to 3500 nm range. In this wavelength range e.g. CH4, C2H6, C2H2, C3H8 and other hydrocarbons can be detected with particularly high sensitivity, since the detection sensitivity typically increases at long wavelengths. Overleaf data for DFB lasers optimized for C3H8 detection isshown as an example.

general ratings (T = 25 °C)

nanoplus DFB laser diodes at 3370 nm
A wide variety of gas molecules, defects in solids etc. exhibit characteristic absorption lines in
the near infrared. DFB lasers emitting at 3370 nm are perfectly suited for highly sensitive detection of small C3H8 concentrations. For this application, highly stable laterally and longitudinally single mode lasers are required.
This data sheet reports performance data of nanoplus DFB lasers at this wavelength. Similar
performance data are obtained in the entire wavelength range from 2900 nm to 3500 nm. For
examples of performance data of nanoplus lasers in other wavelength ranges, please see
www.nanoplus.com or contact sales@nanoplus.com.
