DFB Laser Diodes
DFB laser diodes from 1270 nm to 2400nm
1270 - 1630 nm
1650 - 1700 nm
1700 - 2050 nm
2050 - 2400 nmSince the wavelength of a laser diode is tuned over specific absorption lines of the gas a small linewidth and mode-hop free tunability is important. That makes DFB lasers to the right choice for all gas detection applications enabling the exact measurement of the degree of transmission which is related to the concentration of the specific gas. A high power is important – especially for demanding applications to ensure very precise measurements.
We recommend laser diodes with isolators and thermal management that enable the adjustment of the exact wavelength. Depending on your specific needs, we offer different types of DFB lasers for gas and vapor detection with isolator, collimator, fiber or free beam– all in different package types.
VCSEL/DFB
760nm/763nm Single mode VCSEL/DFB with Peltier Element and Thermistor in TO package
760nm/763nm VCSEL/DFB are designed to meet the requirements for the optical measurement of oxygen concentration levels as well as other spectroscopic applications. The laser emits a single transverse and longitudinal mode with stable linear polarization, small divergence and a highly symmetrical Gaussian beam shape. The hermetically sealed TO-package contains a tilted window and features an integrated peltier element and thermistor.
