The world's brightest laser — which is so powerful that it can produce light pulses that are 1 billion times brighter than the surface of the sun — can "transform" visible light into X-rays, making the shape and color of objects appear different, new research shows.
These X-rays could be much less harmful than current computed tomography (CT) machines and provide much-higher-resolution images, the researchers said.
In the new study, published online June 26 in the journal Nature Photonics, a team from the University of Nebraska-Lincoln led by physicist Donald Umstadter described an experiment they had conducted using their superpowerful Diocles laser, named after an ancient Greek mathematician.
