Highlights from Opto and Laser Europe, July 2000
Consultants and suppliers question train signal claims Claims made by the UK's rail operator Railtrack that its signal lights conform to the International Commission on Illumination's (CIE) recommendations have been questioned by its signal suppliers and external technical consultants. The allegations follow a story in last month's issue (OLE June... view more... (2000-06-23)
Lasers in car manufacture
Lasers play a key role in modern production - for such tasks as cutting sheet metal to size, welding containers and trimming circuit . But their potential is far from exhausted. The automobile industry is playing a pioneering role in the introduction of new laser types and machining processes. The Fraunhofer Institute for Laser Technology ILT in... view more... (1999-07-01)
Tiny infrared laser holds promise as weapon against terror
The difficulty of detecting the presence of explosives and chemical warfare agents (CWAs) is once again all too apparent in the news about the London bombings. view more (2005-08-08)
Diode laser could be vital for safeguarding aircraft
Terrorists can strike anywhere, at any time, and aircraft, both military and civilian, are targets for heat-seeking missiles, one of many tactics in use by groups hostile to the United States. view more (2006-09-01)
Helia Wraps-up Optical Coatings
A new Scottish multi-million pound photonics company is geared up for the future of telecommunications after securing a seven figure private investment deal. The investment has allowed Helia Photonics Ltd, a Heriot-Watt University spin-out to purchase the coatings division of Terahertz Photonics in a technology transfer deal, and say they are... view more...

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)
BUSM researchers identify better laser for treating facial spider veins
Researchers from Boston University School of Medicine (BUSM) have concluded that the 940nm wavelength laser is superior for treating facial spider veins (telangiectasias) as compared to the 532nm wavelength laser. view more (2009-10-07)
Scientists break light modulation speed record -- twice
Researchers have constructed a light-emitting transistor that has set a new record with a signal-processing modulation speed of 4.3 gigahertz, breaking the previous record of 1.7 gigahertz held by a light-emitting diode. view more (2009-06-16)
Researchers generate hydrogen without the carbon footprint
A greener, less expensive method to produce hydrogen for fuel may eventually be possible with the help of water, solar energy and nanotube diodes that use the entire spectrum of the sun's energy, according to Penn State researchers. view more (2008-07-16)
Most powerful laser in the world fires up
The Texas Petawatt laser reached greater than one petawatt of laser power on Monday morning, March 31, making it the highest powered laser in the world, Todd Ditmire, a physicist at The University of Texas at Austin, said. view more (2008-04-08)
Blue laser - the alpha and the omega
The future of DVD is blue. New, low-cost optical laser technology generates short-wavelength beams. At the other end of the beam are detector heads that will soon contain arrays of up to 25 sensors. Two Fraunhofer Institutes are taking the lead at both ends of the spectrum. Man's appetite seems to be insatiable. In the dark ages, packing away... view more... (2004-05-14)
Scientists at the University of the Basque Country succeed in cooling solid material with laser
A team of researchers at the University of the Basque Country (UPV/EHU) have experimentally demonstrated something that other scientists have been trying to achieve for decades: the cooling of erbium-doped materials with laser light. view more (2006-07-27)
Laser treatment
Researchers in Russia have used laser treatment to cure male sexual dysfunction. The Institute of Physics magazine - Opto & Laser Europe - reports this week that after treatment with a device developed by Ekaterina Koultchavenia of the Novosibirsk Research Institute, all 24 male patients in the trial re-gained the ability to have spontaneous... view more...

UCSB researchers develop hybrid silicon evanescent laser
In what promises to be an important advance, researchers at the University of California, Santa Barbara have developed a novel laser by bonding optical gain layers directly to a silicon laser cavity. view more (2005-11-16)
World's most powerful ultraviolet laser inaugurated
Titania will be the most powerful ultraviolet laser world-wide and has the capacity to generate up to 10 terawatt power in single pulses of duration down to 300 femtoseconds. It will be inaugurated at a special ceremony today (Tuesday 2 April) by Dr Paul Williams, Chief Executive of CCLRC, who will fire the new facility's first shot. Titania is... view more...

UK researchers announce continuous Terahertz emission innovation
Researchers at the University of Leeds' Institute of Microwaves and Photonics have developed a novel way of generating continuous tunable Terahertz (THz) radiation. view more (2002-11-14)
Scientists in Japan design first optical pacemaker for laboratory research
The world's first optical pacemaker is described in an article published today in Optics Express, the Optical Society's open-access journal. A team of scientists at Osaka University in Japan show that powerful, but very short, laser pulses can help control the beating of heart muscle cells. view more (2008-05-28)
Dual-focus lenses cut thick metal fastest
V&S Scientific, the UK company that licenses the technology from the Force Institute in Denmark, says that demand for the dual focus lenses is beyond expectation, even though they cost much more than conventional optics for laser cutting. The company exceeded its 1999 sales projections for the lenses by the Spring, reports the July issue of Opto... view more... (1999-06-30)
Catching the wave — Researchers measure very short laser pulses
Scientists have perfected a technique for very accurately measuring and controlling the electromagnetic waves within some of the shortest laser pulses ever made, says new research published today. view more (2006-12-04)
