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)

Ultra-fast, ultra-intense laser has clean-cut advantage
Many people equate lasers with a sci-fi battle in a galaxy far, far away or, closer to home, with grocery store scanners and compact disc players.   view more (2008-03-14)

Fine-tuning lasers to destroy blood-borne diseases like AIDS
Physicists in Arizona State University have designed a revolutionary laser technique which can destroy viruses and bacteria such as AIDS without damaging human cells and may also help reduce the spread of hospital infections such as MRSA.   view more (2007-11-01)

Laser Surgery Probe Targets Individual Cancer Cells
Mechanical engineering Assistant Professor Adela Ben-Yakar at The University of Texas at Austin has developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases.   view more (2008-06-25)

Scientists create metal that pumps liquid uphill
In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists at the University of Rochester have created a simple slab of metal that lifts liquid using the same principle-but does so at a speed that would make nature envious.   view more (2009-06-03)

Ultra-Intense Laser Blast Creates True 'Black Metal'
"Black gold" is not just an expression anymore. Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black.   view more (2006-11-22)

Regular Light Bulbs Made Super-Efficient with Ultra-Fast Laser
An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester.   view more (2009-06-01)

Laser blasts will reveal structures and dynamics of molecules in the fastest events in nature
A new £2 million Research Centre at the University of York will provide unprecedented information on how molecules change, helping scientists understand the structure and dynamics of liquids, proteins and even our DNA. The York Centre for Laser Spectroscopy and Photochemistry opened today (29 October 2003), will use ultra-short laser light... view more... (2003-10-27)

Nano technique allows precise injection of living cells
Specialized pulsed lasers have been used to inject individual cells with a variety of materials, but little is known about how this type of injection might affect living cells.   view more (2007-06-18)

Purdue 'milestone' a step toward advanced sensors, communications
Engineers at Purdue University have shown how to finely control the spectral properties of ultrafast light pulses, a step toward creating advanced sensors, more powerful communications technologies and more precise laboratory instruments.   view more (2007-08-02)

Vibrations key to efficiency of green fluorescent protein
University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel Prize in Physiology or Medicine.   view more (2009-11-12)

Pitt researchers see electron waves in motion for first time
Both the ancient art of stained glass and the cutting-edge field of plasmonics rely on the oscillation of electrons in nanosized metal particles. When light shines on such particles, it excites the electromagnetic fields on the metal's surface, known as "surface plasmons," and causes its electrons to oscillate in waves-producing the rich... view more...

Laser pulses control single electrons in complex molecules
Predatory fish are well aware of the problem: In a swarm of small fish it is hard to isolate prey. A similar situation can be found in the microcosm of atoms and molecules, whose behavior is influenced by "swarms" of electrons.   view more (2009-09-02)

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)

Ready to go: mobile terahertz devices
Terahertz waves, which until now have barely found their way out of the laboratory, could soon be in use as a versatile tool. Researchers have mobilized the transmitting and receiving devices so that they can be used anywhere with ease.   view more (2008-04-09)

Ultrafast laser spectrometer measures heat flow through molecules
Global warming isn't the only heat scientists are feeling. Another area in which heat flow is becoming crucial is the field of molecular electronics, where long-chain molecules attached to tiny electrodes are used to transport and switch electrons.   view more (2007-08-10)

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)

Results with newer bladeless LASIK equivalent to standard microkeratome LASIK
A Mayo Clinic study comparing femtosecond (bladeless) and mechanical microkeratome LASIK surgeries has found equal results from both types six months post-surgery, using a variety of vision and eye health measurements.   view more (2006-05-04)

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...
