Researchers Demonstrate High-Power, Aluminum-Free Mid-IR Laser
Oct 1, 1997 — Scientists at Northwestern University's Center for Quantum Devices in Evanston, Ill., have demonstrated an aluminum-free diode laser that emits up to 3 W at 3.2 µm. In comparison, similar aluminum-free diode lasers have a maximum output of 100 mW, according to the center's director, Manijeh Razeghi. The laser's far field is 12° compared with 60° or 70° for typical diode lasers, she said. This translates to a brighter, more focused beam. The diode laser could find its way...
Researchers fired up about infrared alarm
Oct 1, 1997 — WEST LAFAYETTE, Ind. -- The old adage "Where there's smoke, there's fire" could give way to "Where there's flickering infrared radiation, there's fire," if researchers at Purdue University have their way. They have developed a fire detection device...
Researchers Grow Ultrapure Crystals in High-Vacuum System
Oct 1, 1997 — Scientists have long known that the fewer impurities there are in a semiconductor material, the faster electrons can travel through it. Impurities act as roadblocks, scattering and reducing their speed. Recently a team of researchers led by Mordehai...

Scientists Construct Model to Illustrate Behavior of Optically Excited Materials
Oct 1, 1997 — A group of researchers based at the University of Rochester and led by Shaul Mukamel has developed a set of theoretical models that illustrate how properties of both small and large molecules change when optically excited. Up until this point,...
Sensor reveals steak freshness
Oct 1, 1997 — SWANSEA, UK -- Scientists have developed an inexpensive thin-film oxygen sensor with emission bands in the visible region that fluoresces under a simple UV light source. The sensor could have widespread applications in detecting oxygen contamination...
Sensors Made Light-Sensitive
Oct 1, 1997 — The Consumer Systems Group of the Motorola Semiconductor Products Sector in Chandler, Ariz., and Eastman Kodak in Rochester, N.Y., have developed a tiny filmless camera using Motorola's patented ImageMOS technology. ImageMOS is used to produce...
Anemometer Adapted for Reactors
Sep 1, 1997 — PITTSBURGH -- A device that measures steam velocity in high-pressure, high-temperature environments could be key to ensuring the safety of nuclear reactors within their core. In a collaboration among Westinghouse's Science & Technology Center,...
Germans Measure Quantum States of Squeezed Light
Sep 1, 1997 — KONSTANZ, Germany -- More than a decade ago, scientists discovered a new state of light that, if harnessed, promised to increase the sensitivity of interferometers and other photonic instruments. There was only one problem: "Squeezed light" existed...
Holographic Camera Users Wanted
Sep 1, 1997 — MD Diffusion of Schiltigheim, France, is looking for volunteers who use holographic cameras to test the company's new silver-halide (AgBr) emulsion films. The company's goal is to develop the halide films, which offer fine-grain emulsion, and...
Jellyfish Genes Eyed for Optical Storage
Sep 1, 1997 — SAN DIEGO -- For the next generation of optical storage technology, scientists at the University of California are looking to the sea. A report published in Nature describes newly discovered properties of the green fluorescent protein that gives...
Lucent Demonstrates 100-Channel Amplifier
Sep 1, 1997 — VICTORIA, British Columbia, Canada -- Lucent Technologies has demonstrated a 100-channel optical amplifier that could revolutionize optical networking technology, according to the company. The experimental ultra-wideband optical fiber amplifier can...

Sep 1, 1997 — SAN JOSE, Calif. -- Semicon West '97, an international exposition highlighting innovations in the semiconductor equipment and materials industry, brought the latest developments in wafer processing and integrated circuit test, assembly and packaging...
Marriage of Laser/Arc Welding Promises More for Less
Sep 1, 1997 — HAIFA, Israel -- Plasma-Laser Technologies (PLT) Ltd. has coupled arc plasma and a laser beam to produce a cutting and welding tool that offers more than just the sum of the two systems. The notion of augmenting a laser beam with a plasma arc for...
Multimedia Electronic Imaging Makes Strides
Sep 1, 1997 — The Heinrich Hertz Institut in Berlin has developed a video decoder chip that takes image data and prepares it for display in high-definition television systems. The HDTV-MPEG2 video decoder chip is being implemented in cooperation with Fujitsu...
Optem International

Photonics Center Holds Inaugural Symposium
Sep 1, 1997 — The Boston University Photonics Center will hold its first symposium, "Photonics: Driving the Economy of the Future," on Thursday, Oct. 23. Speakers include representatives from Lockheed Martin, Polaroid, Hewlett-Packard and Corning. Mary Good,...
Photorefractive Polymer Provides High Optical Gain and Long Lifetime
Sep 1, 1997 — SAN DIEGO -- Scientists have unveiled a durable, optically efficient polymer that improves on several years of research toward an inexpensive photorefractive material. Moreover, they have demonstrated its use as an efficient phase conjugated mirror,...
Princeton Develops Organic Laser
Sep 1, 1997 — Researchers at Princeton University in New Jersey have developed a laser from vacuum-deposited organic thin-film materials. Organic lasers have been eyed for years as a possible replacement for inorganic semiconductor diode lasers. Potential...
Report Reveals Pitfalls of Laser Astigmatism Measurement
Sep 1, 1997 — AUBURN, Calif. -- Scientists using a common method of measuring the astigmatism, or optimum focal length, of laser diodes have been led astray, according to a report released by researchers at Coherent Inc. Measuring astigmatism is vital to the...
Sensor Warns of Biological Warfare
Sep 1, 1997 — WASHINGTON -- Researchers at the Naval Research Laboratory's Center for Bio/Molecular Science and Engineering have developed a multichannel biosensor capable of providing early detection of anthrax and other lethal biological agents. Now in advanced...
