mirSense Lasers

mirSense came into being in 2015 after years of developing the QCL technology, providing mid-infrared (MWIR) and long-infrared (LWIR) range laser sources. The QCLs designed and manufactured by mirSense are high-powered diodes (typically watt-level from ≈ 100 mW up to 750 mW), emitting in the main transmission bands of the atmosphere (4.0, 4.6, 4.8, 9.x µm), with new options becoming available deep into the LWIR region (≈ 10-14 µm & ≈ 17-19 µm). 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 is committed to developing and making cutting-edge laser technologies available to everyone every day. From protecting people to protecting their environment, we build tools that allow everyone to breathe cleaner air, move safely, and live in good health.

Quantum cascade lasers are advanced technology resulting from the conquest of space, precise at the atomic scale.
