laser light News
Laser Light Controls X-Rays
BERKELEY, Calif., March 29, 2010 — By changing the material medium through which x-rays pass, scientists are using laser light to control x-ray beams. The team of scientists was led by Thornton E. Glover of Lawrence Berkeley National Laboratory’s Advanced Light Source (ALS), and included Linda Young of Argonne National Laboratory and Ali Belkacem of Berkeley Lab’s Chemical Sciences Division. As a new generation of powerful light sources comes online, intense x-ray beams may be able to control matter directly...
Ultrafast Optical Communications
DAVIS, Calif., March 23, 2010 — A new device could make it much faster to convert pulses of light into electronic signals and back again. The technology, invented by engineers at the University of California – Davis, could be applied to ultrafast, high-capacity communications,...
Golden Bullet Targets Cancer
ST. LOUIS, March 15, 2010 – The mythological silver bullet has just been turned gold. A highly targeted medical treatment, known as the silver bullet, the magic bullet or the Zuberkugel, has become a focu...
All-Solid-State Cryocooler Realized
ALBEQUERQUE, NM, Feb. 2, 2010 – The first-ever all-solid-state cryocooler, which allows coolers to reach temperatures so cold that they can only be obtained by liquefying gases, has been created for applications in airborne and spaceborne sensors. The team, led by University of...
NIF Achieves Historic Laser Shot
LIVERMORE, Calif., Feb. 1, 2010 – Scientists at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) have delivered a historic level of laser energy – more than 1 megajoule – to a t...
Quantum Signatures of Chaos
TUCSON, Ariz., Oct. 9, 2009 – No one has produced experimental evidence that chaos occurs in the quantum world – the world of photons, atoms, molecules and their building blocks – until now. In a series of experiments, professor Poul Jessen and a group at the University of...
Mobius Laser Used at Max Planck
Oct 2, 2009 — Santa Clara, Calif.-based Mobius Photonics, producer of short pulsed fiber laser sources (IR, green, and UV), announced that its G1+ laser system has been used in stimulated emission depletion (STED) microscopy experiments at the Max Planck...
Lasers Aid Supernova Search
GOTHENBURG, Sweden, Aug. 12, 2009 -- One single atom of a certain isotope of hafnium found on Earth would prove that a supernova once exploded near our solar system. The problem is how to find such an atom among billions of others. Now researchers at the University of Gothenburg have...
Yb Tops Cesium in Superclock
GAITHERSBERG, Md., Aug. 12, 2009 – An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation's civilian time standard. Scientists at...
'Drops' of Gold Burn Tumors
BARCELONA, Spain, July 21, 2009 – French researcher Romain Quidant proposes applying laser light to gold nanoparticles inserted into tumor cells, heating the particles to such a degree that the damaged cells would be completely burnt.
Ion Trap Senses Force, Light
GAITHERSBURG, Md., July 6, 2009 – Miniature devices for trapping ions are common components in atomic clocks and quantum computing research. Now, a novel ion trap geometry demonstrated at NIST holds promise as a stylus for sensing very small forces and light particles for quantum...
Get ready for laser-powered 3-D TV
IRVINE, Calif. – Last October, Mitsubishi Digital Electronics America Inc. announced that it was bringing to market laser-powered television. Called LaserVue, it lights up the screen with high-color-purity red, green and blue laser light instead of white lightbulbs...
Lasers Induce Brain Waves
CAMBRIDGE, Mass., April 27, 2009 – Researchers at MIT used a new technology called optogenetics, which combines genetic engineering with light to manipulate the activity of individual nerve cells, to induce gamma waves in mouse brains. The resulting information about neuron function...
Spiral Microlasers Theorized
WASHINGTON, Jan. 26, 2009 – Theoretically, disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Typically, a perfect disk will spray light out, not as a beam, but rather in all directions. According to the Optical Society of...
Ultracold Atomic Gases
BOULDER, Colo., Aug. 6, 2008 – A newly discovered method of photoemission spectroscopy may soon help create a more efficient transmission of electricity across powers grids, and could eventually serve as a building block for some atomic clock and quantum computer designs....
Laser Sorts Moving Droplets in Lab on a Chip
Jun 1, 2008 — A paper by three physicists from Université Bordeaux I in France describes a new and highly effective method of sorting and routing nanolitre droplets flowing through microchannels. The technique will be useful in chemical microreactors and...
Astro-Combing for Planets
CAMBRIDGE, Mass., April 8, 2008 -- The discovery of Earth-sized planets outside our solar system, or "exoplanets," has reportedly been made possible with a laser-measuring device that will advance the resolution of current planet-finding techniques. The new device, called an...
EUV Laser Light Improved
FORT COLLINS, Colo., Jan. 25, 2008 -- The quality of laser light at extremely short wavelengths has been improved dramatically, a discovery that could prove valuable to the semiconductor industry as it aims to develop faster, light-based computer chips. The discovery covers...
II-VI to Acquire Majority Interest in Highyag
Nov 1, 2007 — A wholly owned subsidiary of II-VI Inc. of Saxonburg, Pa., will purchase a 74.9 percent interest in Highyag Lasertechnologie GmbH of Stahnsdorf, Germany, developers of automated equipment that delivers 1-μm laser light for cutting and drilling....
Turning Opaque Materials into Lenses
Oct 1, 2007 — Materials with a milky-white appearance hardly seem a likely choice for making lenses. Any light that manages to penetrate such materials comes out the other side in a faint, random speckle pattern. By shaping the wavefront of laser light entering...
Eye Safety in the Laser Lab
Aug 1, 2007 — One of the most ubiquitous items on the optical table is the beam block. It gets moved around, sometimes to block a stray reflection, at other times to block a “what if” beam. (What if I miss the mirror?) But despite the beam block’s omnipresence, I...
LBO Secures $1M in Funding, Signs Licensing Agreement
Jan 2, 2007 — Light Blue Optics (LBO) of Cambridge, England, a developer of miniature laser projection technology, announced the closing of a $1 million extension to its seed funding round. Venture capital firm 3i plc led the round, which also included investment...
Cymer, Nikon Mark Shipment of 1000th Excimer Laser Light Source
Dec 21, 2006 — Cymer Inc. of San Diego, a supplier of excimer laser light sources used in semiconductor manufacturing, and Japan-based Nikon, a provider of digital imaging, precision optics and photo technology, announced shipment of the 1000th laser light source...
Ultraintense Laser Blast Creates True 'Black Metal'
Nov. 27, 2006 -- A process involving an incredibly intense burst of laser light that can change the properties of almost any metal to render it black could potentially make everything from fuel cells to a space telescope's detectors more efficient, said the...
PHOTONICS TEXTBOOK
Aug 1, 2006 — The 531-page Photonics and Lasers: An Introduction addresses laser light, light-based communication and the propagation, generation and detection of light. Developed by the author as he taught courses, it is designed to serve as a textbook for a...
