Testing this tech will be helpful for navigation in contested environments where GPS may be degraded or denied,” said Gen.

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

Experiment resolves century-old optics mystery 13 Jan 2009 After 100 years of conflicting experimental results, a team from China believe that it has finally unravelled the puzzle surrounding the ...

ABSTRACT A sodium laser guide star (LGS) experiment for astronomical adaptive optics (AO) using a diode‐laser pumped sum‐frequency laser is described. Results of the LGS experiment from 1997 October ...

Today, laser guide stars are an essential part of any adaptive optics system. Keck installed lasers in 2004; the improved vision led to definitive evidence of a supermassive black hole in the ...
