The laser is available in multiple average power classes, including versions above 1 W, below 500 mW, and below 100 mW. The specified power is the total average optical power across the 3.85 µm to 4.15 µm spectral band. The
Is the 4 µm PowerMir QCL ITAR-free?
Yes. The mirSense PowerMir 4 µm QCW QCL is manufactured in France and is described as ITAR-free. This can simplify procurement and international integration compared with some high-power mid-IR laser sources subject to stricter export controls.
What does QCW operation mean for this mid-infrared QCL?
QCW, or quasi-continuous-wave operation, means the laser operates in high-duty-cycle pulsed mode rather than true continuous wave. For this 4 µm QCL, QCW operation supports pulse frequencies above 500 kHz while improving wall-plug efficiency and reducing thermal load compared with lower-efficiency high-power operation.
