  1. Embeddable “Laser Particles” Key To MIT, Harvard Scientists’ Nano-Imaging

    Scientists at the Massachusetts Institute of Technology (MIT), Massachusetts General Hospital (MGH), and Harvard Medical School have developed a new imaging technique using tiny embedded "laser particles," which emit laser light to illuminate dense tissue. The resulting images are six times higher than what current fluorescence-based microscopes are capable of producing.

  2. Asymmetric Waveguide Makes For An Ultra-Efficient All-Optical Switch

    Scientists at the State University of New York at Buffalo have designed a new optical switch that uses an asymmetric waveguide to let a weaker "switching" control beam control a stronger signal or "output" beam.

  3. Russian Scientists Devise Model To Create Anti-Matter With Lasers

    Russian researchers have created a model calculation on how to create matter and antimatter via ultrahigh-intensity laser pulses.

  4. Zapping Schrödinger’s Cat With X-Ray Lasers To View Detailed Atomic Motion

    Physicists at the Stanford PULSE Institute and the Department of Energy’s SLAC National Accelerator Laboratory have created the world’s most detailed X-ray movie of quantum motion inside a molecule. Their experiment could lead to further understanding of basic functions in living things, such as photosynthesis or vision.

  5. US, UK Military Ready Prototypes For Laser Weapon Systems

    The United States and United Kingdom militaries have announced separate deals to develop and deploy laser weapons aboard naval ships.

  6. FDA Approves Zeiss’ Less Invasive Laser System For Nearsightedness

    The FDA has approved the VisuMax Femtosecond Laser for small incision lenticule extraction (SMILE) procedures, which are indicated for the correction of nearsightedness in patients age 22 and older. Carl Zeiss Meditec (Zeiss) developed the SMILE procedure as a less-invasive alternative to LASIK and PRK surgery.

  7. New Laser Line Generator For High Precision Machine Vision Applications

    Coherent released a new series of StingRay µFocus (Micro Focus) lasers, or laser line generators, designed to enable the detection of smaller features in machine vision applications based on triangulation. StingRay µFocus (Micro Focus) lasers feature a linewidth that is 40% smaller than standard Coherent StingRay products (at the same working distance), and can achieve focused linewidths as small as 20 µm, thus providing increased spatial resolution and the ability to discern finer details.

  8. Reflecting Light Off Mirrored Cantilevers To Measure Minute Forces

    Scientists at the National Institute of Standards and Technology (NIST) Physical Measurement Laboratory (PML) have created optomechanical devices that utilize the momentum of photons to measure seldom-known minute forces.

  9. Russian Scientists Develop A Minimally Traumatic And Inexpensive Ceramic Laser Scalpel

    Scientists from MIPT and their colleagues have developed a novel compact and powerful ceramic-based laser – it will be used as a minimally traumatic and inexpensive laser scalpel for surgical operations, and also for cutting and engraving composite materials.

  10. Ophir Announces Photodiode Sensor For Measuring Power Of Laser Bar Code Scanners And Laser Printer Scanners

    Ophir Photonics Group recently announced the BC20-V1 laser sensor for measuring the power of scanned or intermittent beams. The BC20-V1 is a photodiode sensor that measures any wavelength over the spectral range of 400 – 1100nm. It is the only product on the market that is capable of measuring the power of laser bar code scanners; it also measures laser printer scanners and the peak power of pulsed mode lasers.
