diode lasers News
IR diode lasers boost telecom, material industries
Jan 1, 1998 — Improvements to single- and multimode diode lasers have produced devices that are well suited for a diverse set of applications. During the past several years, diode lasers have achieved higher powers and higher reliabilities over an increasingly...
Laser Diodes:
Jan 1, 1998 — The small size, high reliability, excellent beam quality, low price and negligible operating costs of diode lasers have made them today's most popular laser. High power devices promise to replace many other laser types, while enabling more...
Xerox Makes Colorful Splash with Blue Diode Laser
Dec 1, 1997 — PALO ALTO, Calif. -- A small -- a very small -- spot of color here and there is behind Xerox's development of a blue laser diode. Xerox hopes to use the nitride-based semiconductor technology to create a new line of high-resolution printers. Like...
Diode Lasers Light the Way for Automotive Signal Lamps
Nov 1, 1997 — The high brightness and directionality of laser light allow for the design of a new class of ultrathin, uniquely styled automotive tail lamps. These and other diode laser characteristics have driven the design of thin-sheet plastic optics. Halogen,...
Laser Neural Network Acts as Computer
Nov 1, 1997 — EINDHOVEN, Netherlands -- An optical processing network that uses the effect of external feedback on the output of a laser diode to control processor responses could prove to be the harbinger of the elusive optical computer. The researchers seek to...
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...
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...
Single-Step QC Laser Emits at 8.5 µm
Aug 1, 1997 — In the latest development in quantum cascade laser research, a group of Northwestern University scientists reported an 8.5-µm emission from quantum cascade lasers grown in a single step by gas-source molecular beam epitaxy. In addition, the...
American Blue Diode Laser Pulses Atop Silicon Carbide Substrate
Jul 1, 1997 — DURHAM, N.C. -- Cree Research Inc. has demonstrated a pulsed blue semiconductor diode laser that operates at room temperature -- a first step in a race for a commercial device that would greatly increase optical storage capacity.The company's 403-nm...
Diode Lasers Are at the Heart of Cardiac Monitoring System
May 1, 1997 — CAMBRIDGE, Mass. -- Since 1970, doctors have injected patients with iced saline to measure their hearts' blood output. Periodic injections provide reliable results but do not allow doctors to constantly monitor patients.An infrared irradiating...
Aluminum-Free Diodes Offer Doubled Power Potential
Apr 1, 1997 — Researchers at the University of Wisconsin-Madison and Coherent Inc. have produced diode lasers with aluminum-free active areas, which they expect will operate more reliably than AlGaAs-active diodes and will provide roughly twice the power. Writing...
High-Power Quantum Cascade Laser Works, Chilled, in the IR
Apr 1, 1997 — Researchers at the University of Houston's Space Vacuum Epitaxy Center and Sandia National Laboratories have developed high-power infrared semiconductor lasers that combine standard diode laser and quantum cascade laser technologies. The research...
Diode Lasers Sing Spectroscopy's Tune
Mar 1, 1997 — Environmental issues such as global warming, ozone depletion and photochemical air pollution have increased concern about how pollutants affect the environment. This has led to an increased emphasis on detecting pollutants, understanding their...
High-Power Diode Lasers Earn a New Image
Feb 1, 1997 — The growth and development of continuous-wave high-power diode lasers in the last few years has been phenomenal, enabling many advances in a wide range of applications. Diodes’ efficiency, compactness and cost-effectiveness make them an excellent...
Quantum Dot Lasers Emerge from Semiconductor Rejects
Feb 1, 1997 — OTTAWA -- With an eye toward more powerful and smaller diode lasers, researchers at the National Research Council of Canada in Ottawa recently turned something semiconductor manufacturers consider undesirable into quantum dot lasers capable of...
Laser Firm Gets University License for Marketing Al-Free Laser Diodes
Dec 1, 1996 — EVANSTON, Ill. -- Northwestern University has granted an exclusive license to Semiconductor Laser International Corp. (SLI) of Endicott, N.Y., to develop, manufacture, market and sell aluminum-free high-power semiconductor lasers worldwide for...
