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 […]

Interband Cascade Lasers are now available as a broad gain lasers suitable for use in an external cavity. Interband Cascade Lasers are available 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 […]
Tumor and Lymph Node on Chip
Alpes Lasers joins project on tumor and lymph node on Chip for cancer studies Alpes Lasers is a partner in the recently-launched Tumor-LN-oC project which proposes the development of a tumor-lymph node-on-chip (Tumor-LN-oC) platform composed of 3D tissue models and microfluidic chips.Using sensitive off-chip proteomic and molecular approaches this platform will allow the identification of novel biomarkers characterizing metastatic cells which […]
PWest 2021
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!
Laser Spectroscopy with XT-QCL
A group at the TU Wien and Friedrich-Alexander University, who are partners with Alpes Lasers through the Hydroptics and WaterSpy project, have recently published a paper titled “Polarimetric Balanced Detection: Background-Free Mid-IR Evanescent Field Laser Spectroscopy for Low-Noise, Long-term Stable Chemical Sensing” which uses a QC-XT laser from Alpes Lasers to measure water quality in situ at the Prato water treatment […]

Alpes Lasers will be exhibiting at the EPIC PHOTONICS+ virtual exhibition on Feb. 17-18 2021 – check this space soon for registration information!
Phosphine on Venus
Phosphine (PH3) – a possible biosignature on rocky planets – was detected in significant quantities in Venus’ atmosphere. With absorption spectra in the mid-IR, Alpes Lasers QCLs are uniquely suited for measuring phosphine even at extremely low concentrations. See how our QCLs have recently been used to measure PH3 concentrations.
