Long-Wavelength Infrared Lasers

What are LWIR Lasers?

Long-Wavelength Infrared (LWIR) laser sources include the wavelengths from 9 μm –15 μm. CO2 lasers and Quantum Cascade Lasers (QCL) are the most common lasers in this wavelength spectrum.  Our QCL lasers are available with both single-mode and multi-mode beam profiles, and typically have a free-space output. QCLs in the LWIR wavelengths are ideal for many applications in Industrial markets and are widely used in many various Gas Sensing applications.  Long-Wavelength Infrared lasers emit in the main transmission bands of the atmosphere, between 9.0 µm and 17 µm and are available in the HHL Package, OEM package including the driver, and a turn-key solution.

PowerMir Series

mirSense Product Family

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.

UniMir Series

mirSense UniMir HHLThe 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.
