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.
The PowerMir 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.
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.
The REP 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.
The REP 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.
The PowerMir Series is a long-wavelength, single-frequency, DFB, CW Quantum Cascade Laser based on proprietary technology. The technology’s versatility allows them to address any wavelength between 10 and 18µm in CW and up to 21µm in pulsed mode. now commercially available in a sealed High Heat Load (HHL) package, with integrated collimating lens, thermistor, and thermoelectric cooler (TEC), well suited for integration into systems, or as a stand-alone turnkey system for R&D and detection applications.
