Gas Sensing Lasers

What are Gas Sensing Lasers?

Gas sensing takes advantage of theImage Market Industrial Environmental Monitoring Applications Gas Sensing Molecular Spectroscopy narrow absorption bands that most gasses have in the near-infrared spectral region.  Distributed feedback lasers (DFB) and distributed Bragg reflector lasers (DBR) are widely used as gas sensing lasers due to their ability to be frequency tuned while maintaining single mode operations.   Tunable diode laser spectroscopy (TDLS) can measure the concentration, temperature, and pressure of various gases in-situ under harsh conditions with good time resolution, sensitivity, and selectivity. High temperatures, high pressures, and particle-laden gas streams can be dealt with. TLDS has become the best available technology and state-of-the-art in demanding metrology applications like the determination of trace moisture in HCl or the measurement of NH3 in a stack.  On this page you will find a list of all of the wide range of gas sensing lasers we offer at RPMC, ranging from 760 nm to 2150 nm.
