Jan. 27 (UPI) --University of Rochester researchers have developed a novel beam pattern that promises to lend unprecedented sharpness to ultrasound and radar images. The beam's mathematical pattern ...

A new beam pattern could bring unprecedented sharpness to ultrasound and radar images, burn precise holes in manufactured materials at a nano scale -- even etch new properties onto their surfaces. A ...

Optical tweezers and high density optical storage are just two of the applications that could benefit from compact photonic crystal lasers capable of producing diverse beam patterns on demand.

Beams of light polarized into spirals have been used by scientists in the UK to create intricate patterns on the surface of metals. This is the first time that these “logarithmic spirals” have been ...
