Quantum Cascade Lasers
Quantum cascade lasers (QCLs) are intersubband semiconductor lasers emitting around a center wavelength ranging from the mid-infrared to the long-wave infrared (LWIR).
The QCLs designed and manufactured by mirSense are high-powered diodes (typically watt-level). The PowerMir line emits in the main transmission bands of the atmosphere (4.0µm, 4.6µm, 4.8µm, 9.x µm). Furthermore, the new line of UniMir Distributed Feedback (DFB) QCLs emit in the LWIR spectral region (11.3, 13.4, 14, 14.9 & 16µm). The PowerMir line are Fabry-Perot laser sources operating in the quasi CW regime. In other words, pulsed operation down to few tens of nanoseconds and high frequency above MHz at room temperature. The UniMir line are DFB sources with CW operation. These products exhibit high average power and wall-plug efficiency. Therefore, perfect for counter-measure and other defense applications, as well as gas detection in the nuclear and petrochemical industries.
MirSense offers a full range of ITAR-free products from chip on submount manufacturing to full turnkey systems. For example, for OEM system integrators, mirSense manufactures a packaged diode plugged to a top-notch PCB driver that includes laser control, thermal management and security and safety. To clarify, this packaged diode is the “POEM” system (POEM stands for PowerMir OEM system).
The QCLs from mirSense are proudly manufactured in first-class clean rooms in the heart of the French optics valley on the “Saclay Plateau” near Paris. MirSense focuses on serving industrial customers that require a high level of laser repeatability to ensure good batch-to-batch quality for series-productions. Furthermore, customers will find that mirSense offers a very high beam quality.
