DFB Lasers for Gas Sensing
Norcada specializes in single-mode distributed feedback (DFB) semiconductor diode lasers in the 760nm – 3300nm spectrum region for gas sensing and Tunable-Diode-Laser-Absorption-Spectroscopy (TDLAS) applications.
Near-IR DFB Lasers
Our near-IR DFB lasers cover the wavelength range from 760nm to 1854nm. The near-IR DFB lasers are the most cost effective laser sources for TDLAS applications. Available wavelengths include:
1278nm for HF
1512nm for NH3
1576nm for H2S
1578nm for CO, CO2
1651nm for CH4
1654nm for CH4
1854nm for H2O
*Other wavelengths are available upon request.
Mid-IR DFB Lasers
Our semiconductor mid-IR DFB lasers are fabricated using MBE grown InGaAsSb/AlGaAsSb quantum well structures and the material system is ideally suited for the wavelength region of 1900-3300nm. Mid-IR DFB lasers offer significantly higher sensing sensitivity for many gas species that are of interest to industrial safety monitoring applications. Currently stocked wavelengths for our mid-IR DFB lasers include:
2004nm for CO2
2009nm for CO2 (with carbon isotope C13)
2327nm for CO
2330nm for CO, CH4
2334nm for CO, CH4
2465nm
2476nm for HF
2495nm
2505nm
2683nm for H2O, CO2
3270nm for CH4 (v3R3 line)
3280nm for CH4
*Other wavelengths are available upon request.
Laser Packaging Options
We offer standard TO style packaging and fiber-coupled packaging for our laser products depending on the customers applications. TO style packaging options include TO37, TO39 (TO5), and TO66. All standard packages come with miniature Thermo Electric Cooler (TEC) inside the package to maintain laser temperature stability.
The Butterfly-style package offers the customers fiber-coupled laser output in a single-mode optical fibre which is terminated with a FC/APC type of connector.
Custom Packaging Available
Norcada offers packaging services to customers who have special packaging requirements for their photonic products, including high shock resistance packaging, fiber coupling of long wavelength mid IR lasers up to 6µm, and packaging with integrated collimation lenses.
