Currently, LIGO’s laser power starts at 200 Watts ... They are often used to control light distribution, beam shape, or energy transfer rather than focusing on visual resolution.

A team of physicists, led by Jonathan Richardson from the University of California, Riverside, has made a breakthrough in ...

or the Laser Interferometer Gravitational-wave Observatory (LIGO). Han Woerdman and his team have a Letter on angular deviations of a light beam upon reflection on page 337 of this issue.
