European Project to Handle Higher Data Levels
Sep 1, 1998 — European researchers have announced a plan to implement a single, all-optical switching system in response to rising data traffic in telecommunications systems. The electronic switching layers between optical networks form a bottleneck that limits data transmission. To eliminate the problem, European countries would have to invest in an array of electronic technology solutions such as asynchronous transfer mode cross-connects and switches. A switchless optical network could provide a suitable...
Femtosecond Laser Explores Superdense Matter
Sep 1, 1998 — Researchers at the University of Michigan at Ann Arbor have used a high-resolution femtosecond laser that delivers trillions of watts to observe how and when electrons and atoms configure themselves in superdense environments. The work could lead to...
Observatory Employs New Process in Gemini Mirrors
Sep 1, 1998 — AlumiPlate Inc. of Minneapolis, in collaboration with the National Optical Astronomy Observatory and II-VI Inc. of Saxonburg, Pa., has developed a diamond-turning process that yields the high-quality mirrors necessary for the near-IR spectrograph in...
Laser Catapults Progress in Gene Analysis
Sep 1, 1998 — To better understand how cancers develop, molecular biologists seek to analyze genes at the single-cell level. Lasers have played an important role in capturing individual cells, but it has been difficult to effectively isolate tumor cells from...
Hybrid Detectors Work Fast
Sep 1, 1998 — Using a hybrid photomultiplier, spectroscopists now can measure an optical pulse 17 ns after a thousandfold more intense pulse without having to gate the detector to protect it. This development can reduce the complexity of spectroscopy study,...
New Lasers Push Space-Based Lidar
Sep 1, 1998 — The researchers at the 19th International Laser Radar Conference focused their attention on new lasers for space-based lidar to study atmospheric chemistry and physics. Lidar, which can be rugged enough for space travel, can make measurements day...
Researchers Explore Oxide Materials for Fiber Doping
Sep 1, 1998 — Recently, a team of researchers at Containerless Research Inc. in Evanston, Ill., explored using yttria and alumina compositions to expand the range of fiber lasers in the mid-IR. There was only one problem: Molten oxides that do not contain silica...
Sensor Quickly Inspects Inner Pipe Walls
Sep 1, 1998 — Researchers at Tianjin University and Xi'an Jiaotong University have developed a noncontact laser sensor for inspecting the inner walls of pipes with 80- to 140-mm interior diameters. A HeCd laser illuminates selectively fluorescent dyes,...
Naval Research Laboratory Develops Quantum Well Lasers
Sep 1, 1998 — Scientists at the Naval Research Laboratory's Optical Science Div. have developed several types of semiconductor lasers that emit light in the mid-infrared. One of the secrets behind the design is a new capability called "wavefunction engineering"...
Researchers Observe Newton Rings in Laser Ablation
Sep 1, 1998 — Researchers have examined the brief interval after a laser pulse arrives and before it heats away a material's atoms during laser ablation. Scientists at the University of Essen in Germany studied the effect of a 620-nm, 120-fs laser pulse on...
Sandia Researchers Take Cue from Seashell Design
Sep 1, 1998 — Rarely do scientists mention seashells and optical coatings in the same sentence. That may soon change now that researchers at the US Department of Energy's Sandia National Laboratories and the University of New Mexico in Albuquerque have disclosed...
Optical Sensor Monitors Film Growth
Sep 1, 1998 — Over- or under-stressed thin films means that semiconductor devices, such as quantum well lasers, don't work right. To help remedy this problem, a laser optical sensor, called the multibeam optical sensor, measures stress during a thin film's...
Silver Coating Maintains Reflectance
Sep 1, 1998 — Although the reflectors behind the xenon flashlamps that pump the Nd:glass amplifiers in the National Ignition Facility's 192 laser beams might seem at most a secondary concern, their reliability is important. Lawrence Livermore National...
Physicist Uncovers Secrets of Sonoluminescence
Sep 1, 1998 — For years, researchers have tried to explain the atomic processes behind sonoluminescence, the phenomenon in which ultrasonic waves break against a water bubble's surface and heat gas atoms inside. This rapid heating causes gas atoms to glow....
Airborne Laser Passes Another Test
Aug 1, 1998 — The US Air Force, along with Boeing Co. of Seattle, TRW Inc. in Detroit and Lockheed Martin in Sunnyvale, Calif., has fired a multihundred-kilowatt chemical oxygen iodine laser as part of the Airborne Laser Program. The experiments occurred June 3...
Astronomy Project Produces Images
Aug 1, 1998 — The European Southern Observatory's Very Large Telescope delivered its first scientifically useful images May 25-26. Unit Telescope 1 is the first of four 8.2-m telescopes that will join up to three 1.8-m auxiliary telescopes to compose the 200-sq-m...
Researchers' Paths Cross and a New Laser Is Born
Aug 1, 1998 — In an old vaudeville joke a pursued individual is told: "Head to the roundhouse, they'll never corner you there." And so it is with the so-called whispering-gallery disc laser. With no corners, the radiation goes round and round, eventually escaping...
Researchers Unveil New Technique for Imaging Cells
Aug 1, 1998 — An international team of scientists has refined a method for imaging the chemical components of living cells. Working in collaboration with the National Synchrotron Light Source at Brookhaven National Laboratory in Upton, N.Y., the researchers shone...
Robotic 3-D Imager to Brave Chernobyl
Aug 1, 1998 — Deep inside the Chernobyl nuclear power plant in northeastern Ukraine, the site of the worst nuclear meltdown in history, is a room filled with radioactive slag that has kept man and machine at bay for more than a decade. Now a team of researchers,...
NASA Builds Chlorophyll Measurement System
Aug 1, 1998 — Researchers at the John C. Stennis Space Center have developed an optical system for measuring the levels of chlorophyll in plant leaves that can provide an early warning of plant stress. The system is a test bed for both an optical system, designed...
College Installs High-End Digital Imaging Equipment
Aug 1, 1998 — Franklin & Marshall College, a small liberal arts school in Lancaster, Pa., has installed $130,000 worth of digital imaging equipment in one of its biology labs, in an effort to keep pace with the country's pre-eminent research universities....
NIST Researchers Turn to Cryogenic Radiometer
Aug 1, 1998 — Scientists at the National Institute of Science and Technology (NIST) have constructed a laser power and energy measurement system based on a cryogenic radiometer. Since the 1960s, the institute has built and maintained electrically calibrated...
Sensor Relies on 'Time-of-Flight' Spectroscopy
Aug 1, 1998 — Gary Hieftje and Radislav Potyrailo of Indiana University in Bloomington have designed a "distributed" sensor that uses optical time-of-flight spectroscopy. The scientists operate the sensor by sending a very short pulse of light down the length of...
Device Turns Water, Sunlight to Fuel
Aug 1, 1998 — With current technologies, the Earth's sun could supply all the electricity we need. About 10,000 square miles of photovoltaic panels could generate -- in about six hours of daylight -- a day's worth of electricity for the US, according to John A....
Advances in Polymer Gels Pave Way for Sensors, Displays
Aug 1, 1998 — Physicists at the University of North Texas in Denton have conducted trials using a type of polymer gel called a hydrogel that may play a role in new display or sensor technologies. The hydrogels swell or shrink when environmental stimuli such as a...
