2005-09-16 Ultrasensitive quantum lasers sniff toxins
A Georgia Tech researcher develops an ultrasensitive spectrometer using quantum cascade lasers, waveguides and detectors
2008-03-05 Researchers find way to plug laser gap
Researchers at Binghamton University in New York claim to have devised a strategy to bridge the lasing gap with new materials and architectures that could enable applications not now possible.
2007-12-17 Optical antenna allows submicron laser scans
Co-inventor of the quantum-cascade laser, Harvard professor Federico Capasso, has devised an optical antenna that enables QC lasers to perform submicron scans by focusing the laser's spot with nanoscale accuracy.
2008-05-23 Harvard prof develops room-temp THz laser
A Harvard University professor has demonstrated a heterodyning method cast in nonlinear materials that mixes two easy-to-generate optical frequencies spaced apart at the desired terahertz frequency, resulting in a room-temperature terahertz laser
2014-02-19 Quantum cascade THz laser tops power record at 1W
University of Leeds researchers have built a compact quantum cascade terahertz laser, using a semiconductor material of between 1,000 and 2,000 layers.
2010-12-06 SPIE Journal details advances in QCL for detection, monitoring, analysis
The accelerated pace of development of quantum cascade laser technology is the subject of a highly anticipated special section just published in SPIE journal, Optical Engineering, having U.S. Naval Research Laboratory scientists Jerry Meyer and Igor Vurgaftmanare as section editors.
2010-11-10 New long wave infrared lenses for security applications debut
LightPath Technologies unveils focal length and thermal imaging lenses for security products
2008-07-16 Beyond supercool: room-temperature THz lasers
A heterodyning method, cast in nonlinear materials, mixes two optical frequencies whose difference is the desired THz frequency, resulting in a room-temperature THz laser. This may act as scanner like x-rays safe for people and can detect hidden weapons, toxic materials present in the air or distinguish improvised explosive devices at a distance
