Scientists Report High Efficiency in Semiconductor Diode Laser
Jun 1, 1998 — Researchers at Semiconductor Laser International Corp. in Binghamton, N.Y., recently demonstrated an 808-nm, high-power semiconductor diode laser with an efficiency of 56 percent operating at 25 °C. The company's engineers altered the design of...
Solid-State Lasers Join the Space Race
Jun 1, 1998 — In the 60s and 70s, scientists had carte blanche to develop space instruments. However, in todayis cost-conscious space programs, laser designers look towards Earth and improving commercial technologies to meet cost guidelines and accomplish mission...
Tunable UV Free-Electron Laser Achieves Short Wavelength
Jun 1, 1998 — In trials at Duke University in Durham, N.C., a Russian-built tunable ultraviolet free-electron laser achieved 226 nm, a milestone that could portend uses in a variety of medical and physical science experiments. Known as the OK-4 optical klystron,...
Blue Lasers Meet Tough Commercial Requirements
May 1, 1998 — Light-emitting diodes (LEDs) and laser diodes with wavelengths below the red ( Gallium nitride and other III-V nitride-based semiconductors have a direct band gap that is suitable for blue light-emitting devices. The band gap energy of aluminum...
Laser Stops Bose-Einstein Cold
May 1, 1998 — Physicists at Massachusetts Institute of Technology have broken new ground in Bose-Einstein condensate research by trapping the condensate with light and tuning its behavior with magnetic fields. Both accomplishments clear the way for new work in...
Laser Technique Polishes Glass Lenses
May 1, 1998 — Glass's high infrared absorption could prove a boon to a new laser technique that can polish both symmetric and asymmetric glass lenses faster than mechanical techniques. Ferran Laguarta and his associates at the Universitat Politècnica de...
Lasers Restore Classic Cars
May 1, 1998 — The Fraunhofer Institute for Laser Technology in Aachen, Germany, restores classic roadsters, such as vintage Jaguars, using a new laser coating technique. For the last year, engineers have repaired defective turbine components, worn gears and...
Modular Lasers Improve Amplifier Testing
May 1, 1998 — The commercial availability of erbium-doped fiber amplifiers has fueled the explosive growth of dense wavelength division multiplexing optical networks. These multiplexed optical systems in turn place great demands on amplifier performance. This...
Photorefractive Volume Gratings Stabilize Wavelengths
May 1, 1998 — A research team from the National Research Laboratory of Metrology in Tsukuba, Japan, has stabilized the wavelengths of two diode lasers by using two photorefractive volume gratings in one lithium niobate (LiNbO3) crystal. Both wavelengths exhibited...
