A Sonic Boom In The World Of Lasers

It was an idea born out of curiosity in the physics lab, but now a new type of ‘laser’ for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique and highly useful 21st century technology...

...have produced a new type of acoustic laser device called a Saser. It’s a sonic equivalent to the laser and produces an intense beam of uniform sound waves on a nano scale.

....Mau'dib....

Yes - desert mouse!!!!

But will it work in a Sith lightsaber?

more like a Kligon disruptor

You could use that to project sound into someone’s head from miles away.

Simply fire two signals of inaudible sound where the difference is the frequency of the sound you want to project.

Two frequencies will not be heard, but the third (the difference) will appear to come out of nowhere... like a psychotic episode.

This has military applications... you can fire a sound that is the threshhold of pain at people and they will not know the origin.

You can also drive someone mad.

That's been around for 34 years....my wife's voice.

Another possible application would be a sonic-scalpel... perhaps also useful in eye-reshaping (think lasik w/o the cutting of the flap) or disruption of gall-/kidney-stones.

Disruptor...

Baah, we had DI’s at PI that could do that.

That’s why I wear my tinfoil hat, to stop those govm’nt people from tryng to control me with the voices they put into my head.

Even if this sonic version of a laser doesn’t work against field rodents it could still be ping-worthy.

thanks, bfl

Terahertz acoustic oscillations by stimulated phonon emission in an optically pumped superlattice

One of my aunts had a voice that could call hogs two counties away.

nuts, too late to save the sonic fusion crap. ;') Thanks neverdem.

Reminds me of one of the sonic devices in Heinlein's Sixth Column.

The Pan Asians had taken over the US. The "Good Guys" (former military intelligence type) set up a fake religion, then used the sonic device and other higher tech goodies to get rid of the Bad Guys, who could be selectively disintegrated, leaving the local civilians untouched.

But that device didn't use sound waves, it used a gravitic-electromagnetic force.

Still in the experimental stages...

[Danae]

LMAO I was just thinking that LOL

Imagine being able to knock someone on their butt from 1000 yards.

...we feel that the technology has the potential to transform the area of acoustics, much as the laser has transformed optics in the 50 years since its invention.”

Sweet.

Thanks for the ping.
