This data sheet summarizes typical properties of DFB lasers in the range from 760 nm to 830nm. Overleaf data for lasers used for high performance O2 sensing are given as an example.


The following table summarizes the typical DFB laser specifications in the 760 nm to 830 nm range:

DFB laser diodes at 760 nm:

A wide variety of gas molecules exhibit characteristic absorption lines in the near infrared. At about 760nm for example, there is a strong absorption line of O2, which can be used for laser based sensing with very high sensitivity. This data sheet reports performance data of laterally and longitudinally single mode DFB lasers at this wavelength. Similar performance data are obtained in the entire wavelength range from 760 nm to 830 nm.

Application Areas:

High performance gas sensing for process and environmental control
precision metrology
atomic clocks
spectroscopy
space technology
