Long-Wavelength Infrared Lasers: QCL Laser Diodes

Image SWIR MWIR LWIR LaserWhat are LWIR Lasers?

LWIR Lasers or Long-Wavelength Infrared  Lasers emit electromagnetic radiation (laser light) within the LWIR spectral region, which we define as being between ≈ 8 µm and ≈ 15 µm.

PowerMir Series

mirSense Product Family

The PowerMir series is a line of high-power, pulsed Quantum Cascade Lasers based on proprietary technology, available in wavelengths from 4-9 µm and either turnkey benchtop systems, OEM driver + laser module, HHL package, or chip. Our lasers operate in Quasi-Continuous Wave (QCW) mode, enhancing wall-plug efficiency and thermal dissipation. The PowerMir series is ITAR-free, featuring high-powered diodes that emit in the primary atmospheric transmission bands. Our lasers produce a circular TEM00 Gaussian beam for superior performance.

UniMir Series

mirSense UniMir HHLThe uniMir Series is a long-wavelength, single-frequency, DFB, CW Quantum Cascade Laser based on proprietary technology. The technology’s versatility allows them to address various wavelengths between ≈ 10-14um and 17-19um. 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.
