Laser Method Makes Intense Mid-IR Pulsing More Practical
VIENNA, Nov. 24, 2020 — Research efforts from Vienna University of Technology, in collaboration with Harvard University, have led to the development of a laser method that increases the practicality and usability of mid-infrared pulsed lasing. Infrared lasers capable of...
Bursting into sight
Mar 1, 2015 — 3-D movies are cumbersome spectacles. While it’s fun to see our entertainment reaching out to us from the big screen, we are obligated to wear large plastic glasses that, as much as they might try to do otherwise, just get in the way. They...
Sensor Studies Chemicals with Single Chip
VIENNA, June 12, 2014 — Imagine being able to identify and study chemicals through a combined system of laser light and detectors. A tiny sensor, developed by researchers at the Vienna University of Technology, can do just that. Using miniaturized infrared laser...
Combining Technologies Creates Ultrathin Light Detectors
VIENNA, March 28, 2014 — A first-ever combination of technologies has resulted in the creation of an extremely thin light detector.
Control could make random lasers useful
VIENNA – Random lasers, with their very irregular angular emission pattern, are difficult to tune. But a team at Vienna University of Technology has theoretically shown that random lasers can be controlled by actively shaping the spatial pump distribution,...
Controlling Random Lasers
VIENNA, July 15, 2013 — Random lasers, with their very irregular angular emission pattern, are difficult to tune. But a team at Vienna University of Technology has theoretically shown that they can be controlled by actively shaping the spatial pump distribution, giving...
Global Quantum Network Based on Optical Fibers
VIENNA, June 13, 2013 — A technique for increasing the time that quantum information is stored in glass fiber-coupled atoms could yield a global optical fiber-based quantum communication network, researchers in Austria have found.
Light Coupled in Fiber Oscillates Longitudinally
VIENNA, May 29, 2013 — Lightwaves, which typically oscillate perpendicular to their propagation direction, have been seen oscillating longitudinally when coupled into glass fibers, suggesting that light and matter couple much more strongly than previously thought.
CERN detector to measure supershort pulses
VIENNA – Conventional measurement techniques soon will be too slow to measure phenomena taking place on timescales faster than an attosecond. To measure such light pulses, scientists have proposed a method to create the world’s most precise stopwatch....
CERN Detector to Measure Supershort Light Pulses
VIENNA, Nov. 13, 2012 — Conventional measurement techniques soon will be too slow to measure phenomena taking place on timescales faster than an attosecond. To measure such light pulses, scientists have proposed a method to create the world’s most precise stopwatch.
3-D Photografting Grows Bio Tissue
VIENNA, Aug. 27, 2012 — Photografting, a new form of three-dimensional printing that uses lasers to precisely attach molecules at specific places in a material, could soon make it possible to grow biological tissue or to create microsensors.
Coupled lasers cancel each other out
VIENNA – The discovery that coupling two microlasers shuts them both off instead of emitting more light could prove significant for technologies that combine electronics and photonics. The “laser blackout” effect, discovered by scientists at...
Laser detects hidden explosives
VIENNA — Common explosives inside a container can now be detected from more than 100 m using laser light. Specific substances scatter light in a variety of specific ways. This is the basis of Raman spectroscopy and can be used to analyze the contents of a...
Lasers find distant hidden explosives
VIENNA – A new method of Raman spectroscopy uses laser light to detect chemicals inside a container from a distance of more than 100 m. Laser light is scattered in a very specific way by various substances. This is the basis of Raman spectroscopy and can be...
Laser Pulse Reveals Quantum Phase in Electrons
VIENNA, May 16, 2012 — Events that appear to happen instantaneously now can be resolved to a resolution of 10 attoseconds, enabling scientists to look at phenomena that happens on the order of attoseconds (10-18 s), previously far too fast to measure. Researchers at...
Coupling Microlasers Leads to ’Blackout’
VIENNA, April 25, 2012 — By coupling two microlasers together, one would expect more light to be emitted than from a single pumped laser alone. But coupling such lasers can, paradoxically, lead to a "blackout" where they shut each other off.
Lasers Find Distant Hidden Explosives
VIENNA, Feb. 29, 2012 — A new method uses laser light to detect chemicals inside a container from a distance of more than 100 meters.
Magnetized Common Metals Refract Negatively
VIENNA, Austria, Aug. 19, 2011 — While it is generally believed that negative refraction cannot be achieved with natural materials, scientists at the Vienna University of Technology (TU Vienna) report that when common metals such as cobalt and iron are placed in a magnetic field,...
