A smarter way to make ultraviolet light beams
  1. A smarter way to make ultraviolet light beams

    The researchers have optimized an optical resonator to take an infrared signal from relatively cheap telecommunication-compatible lasers and boost it to an ultraviolet beam.

  2. ‘Perfect black’ coating can render a 3D object flat, raises intriguing dark veil possibility in astronomy

    The carbon nanotube carpet is about half the thickness of a sheet of paper and absorbs 99.9 percent of the light that hits it.
