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

The EP series includes tunable single-frequency (DFB-like) diode lasers and Fabry-Perot laser diodes in wavelengths from 1270nm thru 2350nm for communications, sensing and measurement applications. They are enabling new volume markets through the mass deployment of disruptive technologies.

All single mode diode lasers exhibit superior linewidth properties across the entire wavelength range when compared to typical DFB lasers. Utilizing a proprietary discrete-mode (DM) technology ensures excellent side mode suppression ratio (SMSR), without the mode hops inherent to most distributed feedback (DFB) lasers.

The EP Series is specifically engineered for applications such as gas sensing, LIDAR, metrology, and optical communications. Multiple packaging options are available including the Fiber coupled 14-pin butterfly, TO39 (w/TEC), and TO56.

For a complete module incorporating the fiber coupled butterfly package with an integrated current driver and TEC controller, designed for ease of operation, it is the ideal platform for high stability gas detection or remote sensing.  See the DX1 Series.

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.
