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 μm (2820-3070 cm-1) which contains strong absorption lines for CH4C2H6HCl and CH2O (formaldehyde).Contact us at sales@alpeslasers.ch for more information!
