• New ultrafast laser aids astronomers in search for outlying planets
  May 5, 2008, San Jose, CA--Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses, and high average power.
• New coupler technology could assist in enabling tomorrow's silicon photonics
  May 1, 2008, Pine Brook, NJ--Chiral Photonics has announced an advancement in using tapered coupler instead of lensing for low-loss integration of disparate photonic devices.
• Raydiance achieves record pulse energy for femtosecond fiber laser
  April 30, 2008, Orlando, FL--Raydiance has demonstrated the highest pulse energy ever achieved in a fiber laser at the eye-safe wavelength of 1552 nm.
• Startup SUNRGI says it can produce electricity at a rate on par with fossil fuels
  April 29, 2008, Hollywood, CA--A new solar energy system from startup SUNRGI may soon make it possible to produce electricity at a wholesale cost of 5 cents per kWh (kilowatt hour). This price is competitive with the wholesale cost of producing electricity using fossil fuels and a fraction of the current cost of solar energy.
• New testing method analyzes processing in 3D
  April 24, 2008, Munich--The optical 3D measuring system, LensShape, speeds up manufacturing--on display this week at Hannover-Messe.
• Tiny lasers enable more-sensitive chemical detection
  April 23, 2008, Cambridge, MA--Federico Capasso and colleagues at Harvard University are developing a new type of infrared spectrometer that uses a tiny array of quantum cascade lasers on a chip instead of thermal sources to generate the infrared rays.
• University of Utah engineers guide terahertz waves towards far-infrared communications
  April 22, 2008, Salt Lake City, UT--University of Utah engineers took an early step toward building superfast computers that run on far-infrared light: They made the equivalent of wires that carried and bent this form of light, also known as terahertz radiation.
• Tunable metamaterial opens the door for terahertz in multiple applications
  April 16, 2008, Boston, MA--A frequency-agile metamaterial that for the first time can be tuned over a range of frequencies in the so-called "terahertz gap" has been engineered by a team of researchers from Boston College, Los Alamos National Laboratory, and Boston University.
• MPQ scientists apply atomic laser cooling to mesoscopic systems
  April 15, 2008, Garching, Germany--Scientists at the Max Planck Institute of Quantum Optics have already succeeded in the damping of mechanical oscillations of a microresonator by applying the method of laser cooling which has been developed for single quantum particles. Now they have shown that even "resolved-sideband cooling"--a special kind of laser cooling--is applicable to an object consisting of about 10exp14 molecules.
• Femtosecond laser pulses trigger lightning strikes in thunderclouds
  April 14, 2008, Lyon, France and Socorro, NM--A team of European scientists has used high-power laser pulses to deliberately triggered electrical activity in thunderclouds for the first time, according to a paper in the latest issue of Optics Express.
