LWIR (8–15 μm)

LWIR Lasers Overview

LWIR, Long-Wavelength Infrared, 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 the Defense market and are widely used in counter measure applications.  Long-Wavelength Infrared lasers emit in the main transmission bands of the atmosphere, 9.0µm and are available in the HHL Package, OEM package including the driver, and a turn-key solution.

Product Types


QCL Series

QCL Series

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 assembly takes full advantage of MirSense’s state of the art technologies.
