STUTTGART, Germany, Oct. 29, 2013 — Two projects starting next month concerned with developing ultrashort-pulse disk lasers for industrial materials processing applications are receiving €9.14 million (about $12.5 million) in funding from the European Union’s 7th European...
Passively Q-Switched Microchip Lasers Enable Ultrashort Pulses
Mar 1, 2013 — In a world where the micron has become the standard and competition is fiercer than ever, subnanosecond lasers may be just the answer for emerging industrial microprocessing applications. Femtosecond and picosecond laser sources, which have been...
Prism Awards Finalists Offer Solutions to Big Problems
Jan 1, 2013 — Sensors for monitoring environmental toxins and detecting explosives, powerful new lasers for biophotonics, and tools for lithography and spectroscopy are among the finalists for the 2013 Prism Awards for Photonics Innovation, the global competition...
DARPA Seeks Ultrafast Laser Science Proposals
ARLINGTON, Va., Aug. 13, 2012 — DARPA is looking to fund projects to develop ultrafast laser applications including microwave generation, optical time transfer, laser-driven secondary radiation generation and attosecond science through its Pulse (Program in Ultrafast Laser Science...
Low-noise oscillator improves microwave signal stability
GAITHERSBURG, Md. – A new low-noise oscillator generates microwave signals more pure and stable than those from conventional electronic sources. The instrument could improve signal stability and resolution in radar, communications and navigation systems, and in certain...
NEMS Oscillators May Detect Toxins
ITHACA, N.Y., March 18, 2010 - By watching how energy moves across a tiny device Cornell researchers are a step closer to creating extraordinarily tiny sensors that can instantly recognize harmful substances in ...
Laser Trends: Lasers set to blaze new trails
Jan 4, 2010 — As the 50th-anniversary celebration of the invention of the laser begins, the industry itself is making a cautious rebound after months of belttightening, consolidation and reasses...
Medal Winner Talks Lasers
SAN JOSE, Calif., Oct. 14, 2009 -- 2009 has been a special year of advancements for lasers, and by October 2010 the power of the sun could be ever-so-briefly generated in the laboratory. Those are some of the points made during an address Monday by renowned laser scientist Robert L....

OLED Efficiency Improved
DAEJEON, South Korea, July 17, 2009 -- A research team at KAIST (Korea Advanced Institute of Science and Technology) has discovered surface plasmon-enhanced spontaneous emission based on an organic LED (OLED), a finding expected to improve the device's energy consumption, KAIST officials...
Radio Waves Cool Cantilever
BOULDER, Colo., Sept. 17, 2007 -- Physicists have used radio waves to dampen the motion of a thin silicon cantilever containing more than a quadrillion atoms, a cooling technique that has the potential to demonstrate quantum behavior in a macroscopic object using smaller and simpler...
324-GHz Waves Reported
LOS ANGELES, April 17, 2007 -- A 324-gigahertz frequency has been generated using a voltage-controlled oscillator in a 90-nanometer CMOS integrated circuit, a technology used in chips such as microprocessors. The signal generator, which produces frequencies nearly 70 percent...
Carbon Fiber Shows Promise in MEMS Video Displays
ITHACA, N.Y., Aug. 30, 2006 -- Engineers who develop microelectromechanical systems (MEMS) like to make their tiny machines out of silicon because it is cheap, plentiful and can be worked on with the tools already developed for making microelectronic circuits. There is just one...
