QCLs News
How AI Is Advancing the Manufacture of Photonic Systems
Oct 1, 2023 — Many trends in the manufacture of photonic systems are well known: miniaturize and integrate components, scale-up batch sizes, and, increasingly, expand automated and sustainable manufacturing. At the same time, quality control remains a priority but faces ever more challenges, such as zero-defect production or full traceability. Maintaining these goals calls for a “detect/predict/prevent/repair” approach based on comprehensive sensor networks that monitor every step in the production chain as...
Spectroscopy Takes the Long View on Threat Detection
Mar 1, 2022 — When the Perseverance rover landed in Mars’ Jezero crater on Feb. 18, 2021, it represented not only a leap in the search for life on the red planet but also in the identification of deadly chemicals on Earth. Mounted to the rover’s...
Quantum Cascade Lasers Shift from an Emerging to an Enabling Technology
Jan 5, 2022 — Since the unveiling of the quantum cascade laser (QCL) at Bell Labs in 1994, the technology has evolved — from being simply a cutting-edge field in photonics research to being commercially available in the form of packaged lasers, QCL-powered...
Ultrashort-Pulse QCLs Push Possibilities into Mid-Infrared
ZURICH, Dec. 1, 2021 — Researchers at ETH Zurich have demonstrated direct femtosecond pulse emission from a QCL in the mid-infrared region. The demonstration, which the ETH Zurich researchers reported is the first of its kind, opens the possibility for novel applications...
Breakthrough in Terahertz Quantum Cascade Lasers
LEEDS, England, Feb. 13, 2020 — A research team from the University of Leeds and the University of Nottingham believe they have found a way of delivering ultrafast modulation, by combining the power of acoustic and lightwaves. They published their findings in Nature...
Infrared Sensors Offer Insights into Invisible Threats
Dec 30, 2019 — Mark Zondlo has an atmospheric chemistry laboratory at Prince-ton University, but you may have a hard time finding him there. Most of his team’s environmental research is conducted in the real world — roaming through America’s...
Mini-QCL Frequency Combs Provide Solution for Chemical Sensing
VIENNA, Dec. 13, 2018 — Researchers at the Vienna University of Technology (TU Wien) are working with laser frequency combs to enable chemical analysis on a chip. This new patent-pending technology will enable frequency combs to be created on a single chip in a simple,...
Pilot Line Underscores Untapped Potential of Mid-IR Spectroscopy
Oct 24, 2016 — Less than a year after the development stage launch of three photonic pilot lines funded by the European Commission, one of these lines is set to provide open industry access to novel spectrometers operating in the mid-IR range: MIRPHAB...
Block Engineering to Develop QCL System with Pfizer
MARLBOROUGH, Mass., Jan. 21, 2013 — Block Engineering has partnered with Pfizer Inc. to develop a quantum cascade laser based infrared spectroscopy system for noncontact cleaning verification of vessels during pharmaceutical manufacturing.
Block MEMS Wins IED Detection Contract
MARLBOROUGH, Mass., Jan. 4, 2013 — Block MEMS LLC has received a multimillion-dollar contract from the US Army to adapt its LaserScan spectrometer to finding improvised explosive devices from a distance.
Quantum Cascade Lasers Enhance Mid-IR Spectroscopy
Dec 1, 2011 — Voltage-tunable output wavelength, broad gain spectra, high output power and efficiency, and innovative cavity geometries give quantum cascade laser-based sensor systems an edge in applications from gas analysis to chemical sensing. Most vapor...
SPIE Journal Details Advances in QCLs
BELLINGHAM, Wash., Dec. 20, 2010 — The accelerated pace of development of quantum cascade laser (QCL) technology and its many applications — such as detecting explosive chemicals on clothing, monitoring greenhouse gases and measuring blood sugar levels via breath analysis...
Q-On, Laser Components Collaborate on QCLs
Sep 24, 2007 — Laser Components IG Inc. of Hudson, N.H., and Q-On of Vienna, Austria, announced they will work together to develop and manufacture quantum cascade lasers (QCLs). Q-On has taken over the design and processing of wafers, and Laser Components is...
