Quantum Cascade Lasers

ICL External Cavity

Interband Cascade Lasers are available in both DFB format and as a  broad gain lasers suitable for use in an external cavity. You can find here a recent Optics Express article available in open access describing the performance of the external cavity system, or come to Photonics West 2022 to see a talk by the main author in the Novel In-Plane Semiconductor Lasers XXI session.ICL chip BG-3.2-3.6

ICL Single Mode Lasers

Interband Cascade Lasers (ICL) are a mid-IR light source with emission in the 2.7-3.9 μm range, which is important in particular for hydrocarbon detection and other gases of interest. They are now available at the selected frequencies of 2853 cm-1, 2898 cm-1, 2913 cm-1 and 2946 cm-1 (respectively 3505 nm, 3450 nm, 3433 nm and 3394nm).

ICL-based External Cavities

Available Now!

Alpes Lasers now offers Broad Gain Interband Cascade Laser (ICL) chips for use in External cavity systems. ICLs allow emission at shorter wavelengths than traditional QCLs, many of which are particularly interesting for hydrocarbon detection. The initially offered chip covers the range 3.2-3.6 um (2820-3070 cm-1) which contains strong absorption lines for CH4C2H6HCl and CH2O (formaldehyde).
