mirSense Lasers Overview

mirSense came into being in 2015 after years of developing the QCL technology, providing mid-infrared (MWIR) and long-infrared (LWIR) range laser sources. They design and manufacture high-power (typically watt-level) diodes in 4.0, 4.6, 4.8, and 9.Xµm wavelengths for their PowerMir line and 11.3, 13.4, 14, 14.9, 16µm wavelengths for their UniMir line.

The QCLs designed and manufactured by mirSense are high-powered diodes (typically watt-level), emitting in the main transmission bands of the atmosphere (4.0µm, 4.6µm, 4.8µm, 9.x µm), with new options becoming available deep into the LWIR region. They are Fabry-Perot laser sources operating in the quasi CW regime (pulsed operation down to few tens of nanoseconds and high frequency above MHz) at room temperature. They offer high average power, wall-plug efficiency, and beam quality, making them ideally suited for counter-measures and other defense applications.

To assist the nuclear industry in the detection and monitoring of critical compounds, a new class of Distributed Feedback (DFB) Quantum Cascade Laser (QCL) has been developed. While the standard QCL uses InGaAs and AlInAs on an InP substrate – the basis of the optoelectronics telecom industry – this novel QCL technology is based on InAs and AlSb. These materials’ specific properties enabled the expansion of QCL wavelength range from 2.6µm to 25µm, which better encompasses the easily discernable absorption peaks of the compounds of interest. By controlling the chip’s operating temperature through the Peltier element inside the laser’s package, customers tune the emission wavelength without mode hopping, while maintaining single longitudinal mode (SLM) operation. The technology’s versatility allows them to address any wavelength between 10 and 18µm in CW and up to 21µm in pulsed mode, opening the way for high-resolution spectroscopy applications in this spectral range, notably for the detection of BTEX, but also CH3I, HCN and many other compounds.

MirSense, a French manufacturer of QCL lasers, is able to handle anything from small scale development to mass production runs due to their trusted relationship with a local supplier, industrial oriented manufacturing methods, and agile supply chain. Utilizing their highly skilled team of Ph.D. engineers and proprietary, innovative solutions, based on a robust patent portfolio, mirSense brings solutions to customers all over the world.
