Transistor laser functions as non-linear electronic switch, processor
The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and permit its use as a dual-input, dual-output, high-frequency signal processor. view more (2006-02-07)
Laser treatment restores art
FIRING laser beams at priceless paintings might seem the height of folly, putting the painting`s delicate pigments at risk. So while conservators have for decades used ultraviolet lasers to clean up grubby sculptures, they have always fought shy of using them on soiled paintings. But now a study has shown you can fire away with impunity. Lasers... view more... (2002-09-25)
Growing Quantum Dots
Now physicists need not fully control the growth of laser crystals, because the crystals grow themselves. Professor Nikolay Ledentsov and his team at the Ioffe Physico-Technical Institute have learned how to provide special conditions in which crystals can grow defectless. Growing crystals with... view more... (2002-09-09)
Laser-optical mine detection needle will facilitate mine clearing
The "laser-optical mine detection needle" is intended to facilitate the removal of land mines for humanitarian reasons. The working group of Professor Dr. Wolfgang Schade at the Institute of Physics und Physical Technologies at the Technical University of Clausthal intends to exhibit a "laser-optical mine detection needle" at... view more...

Gold nanoparticles prove to be hot stuff
Gold nanoparticles are highly efficient and sensitive "handles" for biological molecules being manipulated and tracked by lasers, but they also can heat up fast-by tens of degrees in just a few nanoseconds-which could either damage the molecules or help study them. view more (2006-09-01)
Lasers Generate Underwater Sound
Scientists at the Naval Research Laboratory are developing a new technology for use in underwater acoustics. The new technology uses flashes of laser light to remotely create underwater sound. view more (2009-09-08)
Nose straightened by laser
A unique methodology that allows to control the form of cartilage tissues in the human organism has been developed by researchers of the Moscow Institute of Laser and Information Technologies Problems, Russian Academy of Sciences. A new methodology is based on strictly controllable heating of cartilages - for example, those of crooked nasal septum... view more... (2003-11-28)

Another world first for Artemis: a laser link with an aircraft
Artemis, the European Space Agency Advanced Relay and Technology Mission Satellite, successfully relayed optical laser links from an aircraft in early December. These airborne laser links, established over a distance of 40 000 km during two flights at altitudes of 6000 and 10 000 metres, represent a world first. view more (2006-12-19)
Quicker, faster, better calibration and machine calibration in the workplace from NPL
The National Physical Laboratory (NPL) is launching a revolutionary new measurement system that will bring laboratory level standards to the shop floor. The technology enables significantly improved calibration times and thereby, minimises machine downtime for industries across the manufacturing sector. view more (2008-04-15)
Hidden structure revealed in characteristics of transistor laser
The transistor laser, invented by scientists at the University of Illinois at Urbana-Champaign, has been full of surprises. view more (2006-04-06)
Researchers putting a freeze on oscillator vibrations
University of Oregon physicists have successfully landed a one-two punch on a tiny glass sphere, refrigerating it in liquid helium and then dosing its perimeter with a laser beam, to bring its naturally occurring mechanical vibrations to a near standstill. view more (2009-06-18)
World`s most powerful laser used as atom smasher - The Physics Congress 2002
Physicists at Glasgow University are using the world`s most powerful laser beam as an atom smasher to simulate conditions inside the Sun and to produce radioisotopes vital in medicine. Professor Ken Ledingham from the Department of Physics at Glasgow and his colleagues from Imperial College and the Rutherford Appleton Laboratory (RAL) are using... view more... (2002-03-26)
Laser Blasts Viruses in Blood
A father-son research team working from separate laboratory benches across the country has discovered a new use for lasers - zapping viruses out of blood. The technique, which holds promise for disinfecting blood for transfusions, uses a low-power laser beam with a pulse lasting just fractions of a second. view more (2007-09-05)
Exploding Bubbles Detected by Laser Light
A revolutionary way of detecting the potentially dangerous gas bubbles in bore-holes that can lead to large explosions, is reported today in the Institute of Physics journal, Measurement Science and Technology. The new technique, developed by researchers at the University of Reading, could save the oil exploration industry millions of pounds by... view more... (2000-05-30)
Laser Therapy Offers Alternative to Surgery for Liver Tumours
Research News in the British Journal of Surgery 11 September 2003: Laser light can be delivered in a controlled and predictable manner to destroy tumours. By inserting fibre optic cables through needles, doctors can direct the powerful laser light onto liver tumours - killing the cells and thus eliminating the need for major surgery. A review of... view more... (2003-09-11)
The little beam that could
Scientists at Los Alamos National Laboratory, in collaboration with researchers from the University of Nevada, Reno, Ludwig-Maximilian-University in Germany, and the Max-Planck-Institute for Quantum Optics in Germany, have developed a new method for using a laser beam to accelerate ions. view more (2006-02-01)
