IRsweep

The IRis-core offers two overlapping free-running QCL-based frequency comb lasers in a single system. It is an ideal basis for setting up a dual-comb spectroscopy system in the mid-IR range. The system outputs already co-aligned beams and comes with a set of drive instructions with factory-characterized heterodyning conditions.

Our IRis-F1 is the first turn-key quantum cascade laser frequency comb spectrometer, and thus contains IRsweep's frequency comb source. The dual-comb light sources are packed into laser modules, which are user exchangeable without tools and with minimum realignment.

The IRcell is a multi-pass cell with a small internal volume of only 38 ml at a path length of 3.5 meters. Its single-piece, single-material construction makes it especially robust against thermal expansion. The IRcell's patented absorption mask efficiently suppresses the fringes otherwise present in the cells.

The IRis-F1 is the first turn-key quantum cascade laser frequency comb spectrometer – a technology offering a combination of broad spectral coverage, high measurement speed, and high brightness. The IRis-F1 can achieve spectral and temporal resolution in a single shot, avoiding the massive experiment repetition required for step-scan techniques. The dual-comb light sources of the IRis-F1 are packed into laser modules, which are user exchangeable without tools and with minimum realignment.
