Gas Sensing Lasers

Gas Sensing Lasers Overview

Gas sensing takes advantage of the 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.

RPMC has years of experience supporting Gas Sensing applications, helping industry professionals select the right tool for the job.

EP Series

EP2108-DM-B: 2108nm DM Laser Diode 1950-2150nm

The EP series is a tunable single-frequency diode laser available in wavelengths from 1270nm thru 2300nm. Utilizing Eblana’s proprietary discrete-mode (DM) technology ensures excellent side mode suppression ratio (SMSR), without the mode hops inherent to most distributed feedback (DFB) lasers.

DX1 Series

EP2051-DM-DX1

The DX1 series is a tunable single-frequency diode laser in a compact turnkey laser system available in wavelengths from 1270nm thru 2300nm. Utilizing Eblana’s proprietary discrete-mode (DM) technology ensures excellent side mode suppression ratio (SMSR), without the mode hops inherent to most distributed feedback (DFB) lasers.

QCL Series

mirSense Product Family

The QCL series is a high power pulsed Quantum Cascade Laser based on proprietary technology which incorporates high-powered diodes (typically watt-level) emitting in the main transmission bands of the atmosphere (4.0µm, 4.6µm, 4.8µm, 9.x µm). The ITAR free MirSense technology exhibits outstanding performance in terms of power and wall-plug efficiency. This high-performance QCL laser assembly takes full advantage of MirSense’s state of the art technologies.

R Series

The R series of wavelength stabilized single mode and multimode laser diodes offer narrow wavelength spectrum in wavelengths from 633nm thru 1064nm. Package options range from components as basic as a TO-56 or 14-pin BF packaged diodes, to OEM modules including electronics, to UL/CE and IEC certified turn-key systems.
