TULLAHOMA, Tenn., July 25, 2012 — A new technique that harnesses the power of femtosecond lasers to seek, acutely map and noninvasively destroy cancerous tumors could benefit brain cancer patients.
Femtolaser Approved for Cataract Surgery
Jul 1, 2012 — Illinois-based Abbott’s iFS advanced femtosecond laser has received FDA clearance for use in corneal and cataract surgeries to create bow-shaped or curved arcuate incisions. The fifth generation of IntraLase technology, the iFS laser creates...
Laboratory lightning strikes more than twice
PALAISEAU, France — With the help of a laser-based lightning rod, laboratory-generated lightning was coaxed to strike the same place not just twice but numerous times, and contrary to the path of least resistance. This advance demonstrates the potential of laser-based...
Atomic 'Billiards Game' Illuminated by Laser
GARCHING, Germany, May 14, 2012 — An international collaboration has observed the occurrence of nonsequential double ionization in argon atoms. In successfully confining the ionization to a single recollision and excitation event, the process can be traced on attosecond timescales....
Hidden 3-D objects imaged
CAMBRIDGE, Mass. – A new ultrafast time-of-flight imaging technique uses reflections from a nonmirrored surface to recover 3-D shapes hidden from sight, essentially allowing the camera to capture images around corners. Scientists at MIT’s Media Lab...
Lab lightning strikes same place more than twice
PALAISEAU, France – With the help of a laser-based lightning rod, laboratory-generated lightning was coaxed to strike the same place not just twice but numerous times, and contrary to the path of least resistance. This advance demonstrates the potential of such rods...
Femtolaser OK’d for Cataract Surgery
ABBOTT PARK, Ill., April 23, 2012 — Abbott’s iFS advanced femtosecond laser has received FDA clearance for use in corneal and cataract surgeries to create bow-shaped or curved arcuate incisions.
Lasers Can Improve Hearing
HANNOVER, Germany, April 20, 2012 — New technologies to improve the insertion techniques and exact fitting of cochlear implants in the inner ear could soon provide better-quality residual hearing for more than 200,000 hard-of-hearing people worldwide.
Laser-assisted Camera Images Around Corners
CAMBRIDGE, Mass., March 21, 2012 — Using reflections from a non-mirrored surface, a new ultrafast time-of-flight imaging technique recovers 3-D shapes hidden from sight, essentially allowing the camera to capture images around corners.
Laboratory Lightning Strikes More than Twice
PALAISEAU, France, March 16, 2012 — With the help of a laser-based lightning rod, laboratory-generated lightning was coaxed to strike the same place not just twice but numerous times, and contrary to the path of least resistance. This advance demonstrates the potential of laser-based...
Femtolaser Pulse Creates 3-D Nanostructures
CAMBRIDGE, Mass., March 9, 2012 — A new fabrication process using femtosecond lasers creates 3-D nanostructures in materials, an essential step toward creating invisibility cloaks and other advanced materials that bend light in unusual ways.
SPIE Presents Green Photonics Awards at Photonics West
BELLINGHAM, Wash., Jan. 30, 2012 — The awards recognized four papers for their innovative research to advance green photonics in the categories of lighting, manufacturing, computing and energy.
FDA Clears Cataract Surgery Laser
SANTA CLARA, Calif., Dec. 30, 2011 — OptiMedica Corp., a global ophthalmic device company, received FDA 510(k) market clearance for its Catalys laser, a next-generation cataract surgery system. Catalys combines a femtosecond laser, integrated optical coherence tomography imaging and...
Terahertz Computed Tomography Helps ID Chemical Substances
Dec 1, 2011 — As radiation sources become more efficient, detectors become more sensitive, and acquisition speeds up, terahertz computed tomography holds promise for nondestructively finding and distinguishing between different materials by visualizing spatial...
Cyborg Bugs as First Responders?
ANN ARBOR, Mich., Nov. 30, 2011 — A device that harvests energy from a bug’s movements could allow cyborg insects — rather than humans — to monitor hazardous situations. The principal idea is to harvest the insect’s biological energy from either its body heat...
Laser Approach Advantageous for Cataract Surgery
ORLANDO, Fla., Oct. 25, 2011 — Two new studies on the use of femtosecond laser procedures in cataract surgery back the argument that the technology may be safer and more efficient than the standard procedures used today. According to data presented at the annual meeting of...
Photonic Solutions Adds Light Conversion Ultrafast Lasers to Portfolio
EDINBURGH, Scotland, Oct. 3, 2011 — Photonic Solutions announced that, with the addition of the Pharos and Orpheus ultrafast laser systems, it has expanded its range of Light Conversion products distributed in the UK and Ireland. The new agreement between Photonic Solutions and...
