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 […]
EPIC PHOTONICS+ virtual exhibition
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.
Monitoring Water Quality using QCLs
WaterSpy is a consortium of 10 partners, including Alpes Lasers, funded by Horizon 2020, the EU Framework Programme for Research and Innovation for 2014-2020 in order to develop water quality analysis photonics technology suitable for inline, field measurements. At the completion of the project in 2020, the WaterSpy module was extensively tested in the labs of partners in Austria, Germany and […]
New Frequency Comb Lasers
Frequency Combs Lasers are now available centered around 6.02 μm, in the amine band, in addition to previously available comb lasers available around 7.95 μm. You can more details in this Optics Express paper as well as in this a sample datasheet.
Gas Sensing aboard drones
The small size and weight of quantum cascade lasers (only ~100 g for HHL housings) make them ideal candidates for integration into remote sensing devices. In this paper published by EMPA an Alpes QCL emitting at 7.83 μm is integrated into a hexacopter drone, achieving a methane concentration measurement with a precision of 0.1 ppb. The system was flown […]
Hydroptics project kick-off
Neuchâtel (Switzerland). EU funded project “Photonics sensing platform for process optimisation in the oil industry”, in short HYDROPTICS, had its official kick-off meeting on the 5thDecember 2019. The projects goal is to increase the competitiveness of the EU oil industry sector, by providing high-accuracy oil-in-water analyzer based on state of the art mid-IR light sources and […]
