Physicists break color barrier for sending, receiving photons

University of Oregon scientists have invented a method to change the color of single photons in a fiber optic cable. The laser-tweaked feat could be a quantum step forward for transferring and receiving high volumes of secured ...

NIST researchers create 'quantum cats' made of light

Researchers at the National Institute of Standards and Technology have created "quantum cats" made of photons (particles of light), boosting prospects for manipulating light in new ways to enhance precision measurements as ...

Clocking Ultra-fast Electron Bunches

(PhysOrg.com) -- Brookhaven researchers have developed a device that acts like a high-tech stopwatch for speedy packs of electrons just trillionths of a second long. This new diagnostic tool could aid in the development of ...

Rainbow trapping in light pulses

Over the past decade, scientists have succeeded in slowing pulses of light down to zero speed by letting separate frequency components of the pulse conspire in such a way that a receptive medium through which the pulse is ...

Making a Magnetic Moment in a Split Picosecond

(PhysOrg.com) -- A wide range of phenomena in nature and technology depend on changes that occur in a material after it is illuminated with visible light. A well-known example is photosynthesis, where successive excitations ...

Laser Fusion and Exawatt Lasers

(PhysOrg.com) -- In the recent past, producing lasers with terawatt (a trillion watts) beams was impressive. Now petawatt (a thousand trillion watts, or 10^15 watts) lasers are the forefront of laser research. Some labs are ...

Lasers generate underwater sound

Scientists at the Naval Research Laboratory (NRL) are developing a new technology for use in underwater acoustics. The new technology uses flashes of laser light to remotely create underwater sound. The new acoustic source ...
