Schott Marks 2 Milestones
SAN JOSE, Calif., Feb. 5, 2009 -- Schott Worldwide celebrated its 125th anniversary, and the 40th anniversary of its Advanced Optics facility in Duryea, Pa., at SPIE Photonics West by introducing several new products to the North American market. Schott Advanced Optics presented new diffractive optical elements for laser beam shaping applications and special short flint glasses especially suited for high apochromatic microscopy lenses. The company's Electronic Packaging business introduced a new hermetic transistor outline...
Schott Marks Two Milestones
SAN JOSE, Calif., Feb. 5, 2009 – Schott Worldwide celebrated its 125th anniversary, and the 40th anniversary of its Advanced Optics facility in Duryea, Pa., at SPIE Photonics West by introducing several new products to the North American market. Schott Advanced Optics presented...
New Laser Type Discovered
PRINCETON, N.J., Dec. 22, 2008 -- The discovery that a quantum cascade laser can generate a second beam with very unusual properties could lead to lasers that operate more efficiently and at higher temperatures than existing devices, for applications including environmental...
Laser Gets Some Bling
SYDNEY, Australia, Dec. 15, 2008 -- A team of physicists at Macquarie University in Sydney has built the first diamond laser using a technique based on the Raman effect. The research could lead to new laser sources that operate over a wide range of wavelengths and with very high power...
LHC: No Smashing Until Spring
GENEVA, Sept. 23, 2008 -- Investigation into the cause of a large helium leak at the Large Hadron Collider (LHC) and repairs to the magnets that quenched during the leak mean the atom smasher won’t restart until spring 2009, officials at CERN, the organization hosting...
Jefferson Lab Upgrade OK'd
NEWPORT NEWS, Va., Sept. 16, 2008 -- Less than a week after the largest particle accelerator in the world launched its first beams near Geneva, Switzerland, the US Department of Energy has approved construction of a $310 million project at the Thomas Jefferson National Accelerator...
TEAM Yields Stunning Images
BERKELEY, Calif., Sept. 11, 2008 -- The world's most powerful transmission electron microscope has been used to produce stunning images of individual carbon atoms in graphene, the two-dimensional crystalline form of carbon that is highly prized by the electronics industry. Using...
Collider Beams Up at CERN
GENEVA, Sept. 10, 2008 -- After 20-plus years of planning, billions of dollars, lawsuits, and even death threats, the first beam of protons in the Large Hadron Collider (LHC) particle accelerator was successfully steered around a 17-mile racetrack at nearly the speed of...
SC Laser Beam Sharpened
CAMBRIDGE, Mass., July 28, 2008 -- A highly directional semiconductor (SC) laser has been developed that could be used for long range chemical sensing in the atmosphere, including homeland security and environmental monitoring, without requiring bulky collimating optics. Applied...
Two-Beam Technique Stores Slow-Light Images in Atomic Vapor
Jul 1, 2008 — If you shine a flashlight’s beam into a fog, you will see the light reflect softly as it disperses through the water particles. Shut the beam off, and the light fades away. Researchers in Israel have found, however, that laser beams and clouds of...
Light Creates Tiny Patterns
PRINCETON, N.J., June 20, 2008 -- The old trick, practiced by schoolboys everywhere, of concentrating a beam of sunlight through a magnifying lens to ignite paper -- or an unfortunate ant -- has been given a new twist. By using a microscopic plastic bead in place of the lens and...
Quantum Images Easily Made
GAITHERSBURG, Md., June 13, 2008 -- A simple and flexible method for creating twin light beams has been used to produce quantum images, visual patterns with features linked by the laws of quantum physics. The method could help with the detection of faint objects, improve the...
Tiny Blinds Bend Beams
CAMBRIDGE, Mass., June 13, 2008 -- A new way of bending x-ray beams could lead to greatly improved space telescopes, as well as new tools for biology and semiconductor chip manufacturing. X-rays from space provide astronomers with important information about the most exotic...
Neurons Imaged Fast in 3-D
HOUSTON, April 28, 2008 -- A technique that combines a laser beam with a multiphoton microscope allows scientists to quickly observe the function of neurons, or nerve cells, in three dimensions, providing a much better view of their fast activity. Scientists at Baylor...
ESRF Finds Oil in Cave Art
GRENOBLE, France, April 23, 2008 -- Light from the European Synchrotron Radiation Facility (ESRF) in Grenoble has proven that ancient paintings found in caves in Bamiyan, Afghanistan, were made with oil, hundreds of years before the technique was thought to have been invented in...
Optical Tweezer Microfabbed
CAMBRIDGE, Mass., Feb. 25, 2008 -- A new type of optical tweezer consisting of a Fresnel zone plate microfabricated on a glass slide can trap particles without using high-performance objective lenses. It has the potential to make biological and microfluidic force measurements inside...
Atom-Moving Force Measured
SAN JOSE, Calif., Feb. 22, 2008 -- The force it takes to move individual atoms on a surface has been measured for the first time, an achievement that could mean future nanoelectronic devices for information technology, medicine and data storage will contain integrated circuits...
Hercules' Power Increased
ANN ARBOR, Mich., Feb. 15, 2008 -- Thanks to an additional amplifier, a laser at the University of Michigan can now produce a concentrated beam of light so intense it is like holding a giant magnifying glass in space and focusing all the sunlight shining toward Earth onto one grain...
'Squeezed Light' Record Set
HANOVER, Germany, Jan. 29, 2008 -- An extremely high-quality green laser beam has allowed a record number of photons to be placed in a specific order for use in gravitational wave detectors. Ordering the photons reduced fluctuations in the intensity of the light by 90 percent. This...
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...
Laser Beam Sorts Cells
CAMBRIDGE, Mass., Dec. 13, 2007 -- Like water from a firehose levitates a beach ball, a new system uses a targeted beam of light to push certain types of cells up out of special "traps." The method could make separating particular cells from a sample faster, cheaper and easier, and...
Si Nanophotonics Advanced
YORKTOWN HEIGHTS, N.Y., Dec. 6, 2007 -- Silicon research announced today uses light instead of copper wires to transmit information through the "brains" on a chip. The development could potentially lead to supercomputers -- which today are power-hungry, huge, and run hot -- that fit into...
Ultrashort Light Pulses Generated
UPTON, N.Y., Jan. 22, 2007 -- Using a titanium:sapphire laser to control the pulse duration of light from a free electron laser, researchers have developed a new technique that generates extremely short light pulses, something they said could be used in the next generation of...
Mechanical Motion 'Spins' Atoms in a Gas
GAITHERSBURG, Md., Dec. 11, 2006 -- For the first time, scientists have used mechanical motion to make atoms in a gas "spin." The technique eventually might be used in high-performance magnetic sensors, to enable power-efficient chip-scale atomic devices such as clocks, or serve as...
‘Tabletop’ Particle Accelerator Built
PASAISEAU, France, Dec. 8, 2006 -- A team of French researchers said they have developed a compact laser-plasma accelerator that uses two colliding laser pulses to produce highly stable and reproducible electron streams. High-energy particle accelerators, which can generate...
