Laser Product Information
Norcada specializes in single-mode distributed feedback (DFB) semiconductor diode lasers in the near-IR and mid-IR spectrum regions 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 1300nm to 1670nm. The near-IR DFB lasers are the most cost effective laser sources for TDLAS applications. Available wavelengths include:
1512nm for NH3
1576nm for H2S
1578nm for CO, CO2
1654nm for CH4
Other wavelengths are also available on custom request. Please contact us for further details.
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 1900-3600nm. 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:
1854nm for H2O
2004nm for CO2
2327nm for CO (high temperature applications)
2334nm for CO
2476nm for HF
3270nm for CH4 (v3R3 line)
Other wavelengths are also available on custom request. Please contact us today to discuss your laser needs for TDLAS applications.
