QC-XT Laser used for CO/N2O/CO2/H2O detection

A team from the University of Bari in collaboration with Alpes Lasers uses a QC-XT laser combined with a quartz-enhanced photoacoustic spectroscopy setup to measure carbon monoxide (CO), nitrous oxide (N2O), carbon dioxide (CO2), and water vapor (H2O) simultaneously. The device emission wavelengths ranged from 2100 cm-1 to 2250 cm-1 and the achieved minimum detection […]

In 2021 the Photonics West exhibition is virtual only but as always we will be present! Come to our booth to chat or discuss via video anytime from March 8th to 11th!

ICL-based External Cavities

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 CH4, C2H6, HCl and CH2O (formaldehyde).Contact us at sales@alpeslasers.ch for more information!

Balloon-borne QCL measurements

Using the lightweigth and small size intrinsic to QCL systems, researchers at EMPA have demonstrated a new Compact and lightweight mid-infrared laser spectrometer for balloon-borne water vapor measurements. This comes on top of their previous achievement of mounting a QCL on a drone!
