MWIR (3–8 μm)

MWIR Lasers Overview

MWIR,  Mid-Wavelength Infrared, laser sources include the wavelengths from 3 μm –8 μm and Quantum Cascade Laser Diodes are the most common lasers in this wavelength spectrum.  These lasers are available with both single-mode and multi-mode beam profiles, and typically have a free space output.  MWIR lasers are ideal for many applications in the Defense market and are widely used in counter measure applications.  Mid-Wavelength Infrared lasers emit in the main transmission bands of the atmosphere, 4.0µm, 4.6µm, and 4.8µm.  Our QCLs are available in the HHL Package, OEM package including the driver, and a turn-key solution.

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.

Q-TUNE Series

Q-TUNE-IR

The Q-TUNE series is a high energy, compact, tunable wavelength laser consisting of an Optical Parametric Oscillator (OPO) capable of producing a tunable wavelength range of 410-2300 nm with a linewidth narrower than 6 cm-1. Optional second harmonic generator extends the tuning range to 210-410 nm.
The combination of a pulse duration shorter than 5ns and an upper repetition rate of 100Hz, makes the Q-TUNE a perfect coherent light source for temporally resolved spectroscopy, metrology, photo-acoustic imaging and remote sensing applications.

Q-TUNE-IR

Q-TUNE-IR The Q-TUNE-IR uses an Optical Parametric Oscillator (OPO) to produce tunable wavelength in 1380 – 4500 nm range with a linewidth less than 10 cm-1, achieving > 6.5mJ of pulse energy @ 3500nm for the F-10 configuration (> 2mJ @ 3500nm for C-10) with a 10Hz repetition rate. A broadband version with linewidth up to 200 cm-1 is also available by request.  The Q-TUNE-IR requires little maintenance, with all laser electronics integrated into the housing, including an air-cooling system, eliminating the need for chillers, or large power supplies, all while providing a guaranteed pump diode lifetime greater than 2 giga-shots.
