[Wired] Pew Pew! Scientists Build Lasers Out of Sound, Call Them Phasers

post #1 of 12

Using a nanoscale drum, scientists have built a laser that uses sound waves instead of light like a conventional laser.

Because laser is an acronym for “light amplification by stimulated emission of radiation,” these new contraptions – which exploit particles of sound called phonons – 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.

Aren't Phasers Masers?

The name proposal is obviously the work of an overly excitable Trek nerd -- you could use the same rationale to call a laser a phaser, since photon : laser :: phonon : saser.

I believe these work the same way as lasers, but with sound phase. in lasers, photons are bounced back and forth until they are all going the same direction in a tube. This probably uses sound waves in a tube (equal to some fraction of the wavelength of sound being used) that are reflected back and forth in such a way that the phases add together over and over until the amplitude is massive.

I didnt read the paper, though. it wants me to buy it.

I've been watching Star Trek Enterprise recently, I saw this and was like "NOOOO WAY". That's some crazy stuff there.

Well that explains why he didn't name the phenomenon after himself. I'm not sure that anyone would take a paper on "Mahboob Rays" seriously.
