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…
Hard light dildos let’s fucking goooo
Man, they’re going to have remake all the Star Wars porn parodies all over again.
Code Bullet? That you?
Light sabers?
Holograms or maybe molecular scale tractor beams?
Yelling lightsabers at that loudness. All the better imho.
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.
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
So like, ten years at most
Horseshit. Don’t piss on my head and tell me it’s raining.
Edit: this is more horseshit like the “room temperature superconductor” that was instantly debunked as a horseshit scheme recently.
Sound pressure waves cannot distort spacetime
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.
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
Doesn’t an AOM typically have a lens?
No, it’s just a crystal and a piezo. You can focus into the AOM to get lower rise times but it works without any lenses.
I think I should have said “optic” in place of “lens”. The crystal is the portion that is being oscillated to divert the beam. It could be that this is exactly the same principle being used by the referenced experiment but with much higher powered acoustic equipment.
Yeah, they’re using air instead of a crystal :D
Why not a BOM?
Why not a BM?
Buero of Meteorology?
Just an AOM, but counting upwards.
Age Of Mempires?
Green laser beams have been deflecting off nothing but air since we invented green lasers. That’s why they are visible without adding smoke.
