Physicists at the California Institute of Technology (Caltech) have developed a nanoscale device that can be used for force detection, optical communication, and more. The device exploits the mechanical properties of light to create an optomechanical cavity in which interactions between light and motion are greatly strengthened and enhanced.
Applied Scintillation Technologies Ltd (AST) reports that over 7000 of its 'credit card' style VISUALIZE® phosphor products were sold in FY 2008/9. The VISUALIZE® (VisualizeIR, VISualize and UVisualize) range of products use specialized phosphor coatings to provide a safe image of the beam for infrared (IR), visible to near infrared and ultraviolet lasers. This addresses the problems of profile measurements and component alignment of laser and laser diode modules.
In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists at the University of Rochester have created a simple slab of metal that lifts liquid using the same principle-but does so at a speed that would make nature envious.
With thousands in attendance, the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory was officially dedicated today, setting into motion the next chapter of one of the country's greatest scientific assets.
An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can.
Solar electricity has a future: It is renewable and available in unlimited quantities, and it does not produce any gases detrimental to the climate. Its only drawback right now is the price: the electric power currently being produced by solar cells in northern Europe must be subsidized if it is to compete against the household electricity generated by traditional power plants.
The UltraPulse CO2 fractional laser was featured today on NBC's Today Show as an exciting and revolutionary new treatment for scars. During the broadcast, triplets who were severely burned in a fire as infants told their personal story and discussed recent treatments with the Lumenis UltraPulse laser.
Researchers from around the world will present the latest breakthroughs in electro-optics, lasers and the application of light waves at the 2009 Conference on Lasers and Electro-Optics/International Quantum Electronics Conference (CLEO/IQEC) May 31 to June 5 at the Baltimore Convention Center in Baltimore.
Over the past 15 years, the availability of high quality sapphire and silicon carbide substrates has enabled the rapid growth of the gallium nitride device (mainly high-brightness LED) market to $4.6 billion in 2008.
By combining the best of two different distance measurement approaches with a super-accurate technology called an optical frequency comb, researchers at the National Institute of Standards and Technology (NIST) have built a laser ranging system that can pinpoint multiple objects with nanometer precision over distances up to 100 kilometers. The novel LIDAR ("light detection and ranging") system could have applications from precision manufacturing lines on Earth to maintaining networks of satellites in perfect formation, creating a giant space-based platform to search for new planets.
