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 (2500cm-1 – 1000cm-1). uniMir lasers operate at room temperature, without a cryogenic system, in pulsed or continuous wave emission.

mirSense uses the well-known Distributed Feedback (DFB) effect and a unique patented approach to achieve single frequency sources. This technology uses top metal grating to provide the feedback in the cavity allowing 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.
