Building gamma-ray lasers powered by an exotic hybrid of matter and antimatter may sound like science fiction, but scientists are now a step closer to doing it.
Whereas the wavelengths of traditional lasers run the gamut from infrared to X-rays, a gamma-ray laser relies on light waves even smaller than X-rays. For instance, the antimatter-powered laser would produce light with wavelengths a thousandth the size of modern-day X-ray lasers, enabling it to probe incredibly tiny spaces and making it useful in medical imaging technology. …more
