uniMir : Single Mode DFB QCL / Broadband Fabry Perot QCL

The uniMir product line offers single mode Quantum Cascade Lasers (single mode DFB QCL) or broadband lasers (Fabry Perrot) between 4µm – 10µm (2500 cm-1 – 1000 cm-1). uniMir lasers operate at room temperature, without a cryogenic system, in pulsed or continuous wave emission.

Single Mode DFB QCL

mirSense uses the well-known Distributed Feedback (DFB) effect to achieve single frequency sources. Furthermore, our products rely on our strong experience (since 2000) and a unique and patented approach. Our technology uses top metal grating to provide the feedback in the cavity. Top metal gratings allow versatility, reproducibility and stability in wavelengths.

uniMir devices can be delivered with standard butterfly or HHL packages on demand. Both packages have integrated thermistance and a Peltier element for the thermal regulation of the laser. Collimated beams are also proposed for an easier integration in your optical system.


Wavelength 4 µm – 10 µm
Mode Pulsed (QCW) or Continous (CW)
Operating Temp. Range 0 – 40°C
Package Butterfly (BTF) or HHL
Line Width 0.001 cm-1 (CW)/  < 1.5 cm-1 (QCW)
*These are typical values and depend on the wavelength.
