Scientists Build Lasers Out of Sound, Call Them Phasers

You have to laugh at people smart enough to make lasers out of sound but can't come up with a better name than "phasers." big grin

Because laser is an acronym for "light amplification by stimulated emission of radiation," these new contraptions آ– which exploit particles of sound called phonons آ– should properly be called phasers. Such devices could one day be used in ultrasound medical imaging, computer parts, high-precision measurements, and many other places.
