Laser Beams Deflected Off of Nothing but Air for First Time Ever in Breakthrough Patent Pending Process - The Debrief::An international team of scientists report that they have successfully used acoustics to deflect laser beams in an engineering first.
140 decibels. I’m sure some applications exist but it won’t be a 3D TV soon.
In an ultrasonic frequency we can’t hear. But your pets and any nearby bats or rodents etc may be upset by it…
Can’t hear but still cause damage?
I didn’t know the answer to this so I looked it up - yes. Over 120 Db can cause damage even if it’s ultrasonic and you can’t hear it. Apparently at 155Db the heat created by the sound wave can be dangerous as well.
Just a small note, it’s written dB, small “d”, big “B”.
“B” is the unit symbol for bel and “d” is the symbol for the SI prefix deci, a tenth.
Oops, thanks for the correction!
i love you
Hard light dildos let’s fucking goooo

Code Bullet? That you?
Light saber what?
“Blow me” about to have a whole new meaning.
Light sabers?
Yelling lightsabers at that loudness. All the better imho.
Fun fact, if sound travelled through space, the sun would be as loud as a jackhammer everywhere on earth. Second fun fact, due to the fact that we evolved on earth you wouldve evolved to not be able to hear that frequency.
Luke!
WHAT?
LUKE! I AM YOUR…
WHAAAT? TURN YOUR LIGHTSABER OFF IF YOU GOT SOMETHING TO SAY
HELL NO YOU TURN OFF YOUR LIGHTSABER BOY
Holograms or maybe molecular scale tractor beams?
Holodecks soon?
considering the lab experiment with just one laser required a sound level of about 140 decibels that consume 20 gigawatts, I don’t think holodecks are going to be a practical device.
WHAT DID YOU SAY? I CAN’T HEAR YOU OVER MY HOLO-WAIFU
“NOTICE ME SENPAI!!1”
Great points, but you know how things go. Proof of concept is a bloated laboratory implementation, then the tech gets smaller and more efficient over time. Next thing you know the sound is outside of human hearing range and the laser projector is fitted to a drone.
More realisticly how things go, experimental research only works in lab conditions, clickbait article suggests it’s coming next year, people make giant assumptions, people lose faith in science because the promised thing doesn’t arrive
Lol probably, we are definitely more on track for cyberpunk or idiocracy than star trek post scarcity socialist utopia
According to the article it’s already using ultrasound.
So they can only do holodeck simulations of EDM shows.
It may be interesting to see how humidity and temperature influence the laser (or even other gases as mentioned in the article)
So like, ten years at most
Space battles would be so much cooler if every now and then the phaser gets split around the ship instead of hitting the shields.
Would also work even when shields are down.
But that needs air. There’s no air in space.
There’s an Air and Space Museum
Doesn’t need to be air “in space”, there just needs to be air somewhere between the laser weapon and whatever it is you don’t want the weapon to destroy…
… although it’d probably be easier to use a mirror. Maybe one pointing directly at the person holding a laser weapon. ;-)
Corner reflector. Send it back where it came from, without knowing where they are ahead of time.
Damn… you’re right.
Maybe they’ll find another way now that they’ve found one.
A mirror? Light won’t reflect off of nothing. The closest you’ll get is gravitational lensing, but that requires about a galaxy’s worth of mass to make any noticeable difference.
I mean, that’s a 20GW laser, what about those handheld lasers? Would you still need 140db?
It would happen regardless of the power of the laser, but it would likely be undetectable at significantly lower power.
That’s just an AOM
Art of Manliness?
Age Of Mempires?
Why not a BOM?
Why not a BM?
Green laser beams have been deflecting off nothing but air since we invented green lasers. That’s why they are visible without adding smoke.
