Hail the first sound ‘lasers’

[fritzd]

Lasers 'Light Amplification by Stimulated Emission of Radiation' has been one of the major reason why our knowledge and advancements in optics and photonics have progressed unimaginably. It has found its applications to everyday portable devices that we use and to highly advanced experimental physics experiments such as Laser cooling down down to the nanokelvin regime, laser induced fusion, quantum key distribution in optical fiber networks, and many more.

As for somebody who is specializing in this, I find this very very interesting and news worthy to share to everyone. On of the most interesting properties of Lasers is its COHERENCE and high energy denstity. This has allowed many optical based measurement techniques to flourish. Sasers or Sound -ASERS which the article below describes works similarly like a Laser only the the output is SOUND and not light.

"Who can resist the analogy, & perhaps it should NOT be resisted:
PASES (phonon amplification by stimulated emission of sound).
I forsee the finest stereo system ever created !" - one of the comments of the article.

never thought sound could also work like lazer .. hehe its cool

mao buh... kuyaw duh

unsa na nga laser, kanang pariha sa mata ni superman.?

so kung sound lng, grabiha gud.. ma tunga imung lawas nga di ka kita naay laser, kay sound ra ang ni gawas.? something like that.?

Don't mix fantasy with reality although there are really lasers that can really cut you half but these so called "sound" lasers aren't like that. It is just the properties of a laser such as spatial coherence coherence and emitting at only a single wavelength.

I guess the main important property of this 'sound' laser is coherence. This will really be useful in metrology experiments. Coherence (physics) - Wikipedia, the free encyclopedia
The idea of a 'sound' laser is just fascinating. SASER

nyahahaha batia sa laser nga naay sound eyys hahaha saba kaayo lol
