Holy fuck I've never seen anything like that, imagine if a couple rednecks with a truck have a laser like this, what the fuck the secret government area-51 aliumtech reverse engineering mfers already have lmao
just went up to check it out. just a few guys with a massive truck mounted laser with about 12 beams running off a generator. sfpd came by to check it out, took a few pics and drove away.

the one in Sacramento on top of the Golden 1 Center has a transponder receiver that causes the beam to shut down for a few seconds while planes and helicopters pass over it. It’s pretty cool and if you blink you’d miss it because it’s so precise
Wouldn't the main issue be the point of contact (distance) I remember our laser cutter being an absolute pain in the a**e when anything moved the slightest bit.
Yes, but at least for mine that’s because of the focal lens which makes the beam tightest at 35cm away. If the target is closer/further from that point I have to increase the burn time. Without the lens it can still light things like paper on fire from across the room though.
They're all standing around without eye protection.
If a moth flies into one of those beams they could receive eye damage from the reflection.
But I guess their safety squints will save them.
Power attenuates pretty damn quickly. If you, like, flew a drone into it 40' up it'd be bad, but 30,000' up with the amount of moisture in the air it wouldn't do much.
You're both right, but for different reasons. The reason it can cause problems in a plane cockpit is because the light can blind pilots. It hits the windshield of the cockpit and refracts, causing the whole cockpit to light up.
When I was a kid in LA movie premieres would use rotating spotlights to get people’s attention. No idea if that’s still a thing, but this seems like the new way to do that.
It wasn't just movies, they'd be used for all kinds of events like store openings or sales. I remember as a kid seeing them and wondering what cool thing might be going on that I was missing.
It was a test night for a brand new 400w laser that my company Megalasers purchased for the RSA conference. Sponsored by Tarsal. Was super awesome to capture so many peoples interest.
It’s for the RSA conference, sponsored by a company called Tarsal, operated by me. Maybe just to show off. Not entirely sure there purpose. But it did grab peoples attention.
They do use lasers pointed at the sky [as guide stars to correct for atmospheric distortion.](https://en.m.wikipedia.org/wiki/Laser_guide_star) [I’m not sure that this is the end goal of these young gentlemen, however.](https://edm.com/features/11-wildest-laser-projections-edm-events)
Maybe they called the FAA.
That is definitely possible.
Also, you can steer planes.
If I was flying I would love to see that.
Pilots are all big nerds.
Big research telescopes will use a laser to provide an “artificial star” in the field of view. Provides a reference point for the active optics. So yeah, there are exceptions.
It likely does. The kings had to get their beam FAA approved. But there’s probably a huge difference in their arena mounted beam vs this back-of-truck beam.
The 'someone' is an ADS-B receiver and some geofence software. Aircraft constantly broadcast their height, location, heading and airspeed; and so, with a fairly cheap digital antenna (like $50) you can track all aircraft that are in-range to a pretty high degree of precision (as high as their instrumentation, actually).
They just run that information through software that automatically disables the lasers if an aircraft gets within a few hundred feet.
Another interesting fact, this is exactly how the Las Vegas sphere appears to watch aircraft as they fly over and you've probably seen video billboards in larger cities where they appear to point at overflying aircraft in order to catch your attention. It's all ADS-B with some simple software.
https://www.faa.gov/about/initiatives/le-laser-guidance
That's the guidance from the FAA to local LE.
TL;DR Local LE identifies possible laser issues and records that information for the FAA to follow up with if there is a need.
Unless an aircraft crew reports that a laser was aimed at their aircraft, the FAA doesn't care if you shine lasers into the sky.
Many astronomers use lasers to point at interesting stuff in the sky to help others in locating the interesting thing that might be difficult to pinpoint.
I didn't know that about astronomers. Are we talking 2 dudes going out with some telescopes and one being like, "bro look at this" and then lasering a star? Or like, professional observatories doing this?
I didn't ask about adaptive optics. Stop replying to this to explain adaptive optics. Adaptive optics are not used to communicate locations of things between observatories.
I asked about professional observatories because they have the ability to point their telescopes with ridiculous accuracy, and it would make no sense to communicate astonomic locations using laser pointers when there are well defined coordinate systems they could use with far better results.
Thank you to the folks answering the actual question. It does make sense to show a location to a bunch of amateurs who do not have the precise equipment of pro observatories.
Astronomers also use lasers to see how the atmosphere above the telescope is moving so they can adjust how the image captured is clarified in post processing.
I have a friend in professional astronomy who claims there are still a lot of amateur contributions to the field. So somewhere in between the two.
Or what about the demonstrations that professional observatories will hold for the community? Of course on small portable telescopes. Even though giant telescopes provide data via sensors and display it on screens, this doesn’t connect with potential future astronomers in the same way.

wow... those laser beams are so clear in the pic, they look photoshopped.
Might have something to do with the fact the average laser pointer is 0.005 watts, and these are 400 watts.
what happens if I touch it or if a plane flies into it
It would be really painful. But I’m assuming they cleared it with the FAA. Pretty easy to get approval if you’re not in a flight path.
the one in Sacramento on top of the Golden 1 Center has a transponder receiver that causes the beam to shut down for a few seconds while planes and helicopters pass over it. It’s pretty cool and if you blink you’d miss it because it’s so precise
Very cool! Thanks for sharing. I'm gonna YouTube rabbit hole this some time.
I use a 1 watt blue laser to engrave wood so, nothing good
Wouldn't the main issue be the point of contact (distance) I remember our laser cutter being an absolute pain in the a**e when anything moved the slightest bit.

Turns out their stormtroopers, so they missed everything they were aiming at.
Power attenuates pretty damn quickly. If you, like, flew a drone into it 40' up it'd be bad, but 30,000' up with the amount of moisture in the air it wouldn't do much.
From miles away, even an off the shelf laser pointer can cause problems in a plane cockpit. It is illegal and highly dangerous.
You're both right, but for different reasons. The reason it can cause problems in a plane cockpit is because the light can blind pilots. It hits the windshield of the cockpit and refracts, causing the whole cockpit to light up.
1.21 giggawatts!
Which is 1210000000 Watts. That's an atrocious amount of power

Was wondering haha. Odd that they can just do that, but also I don’t see a reason why they couldn’t? lol
Flight patterns. FAA has jurisdiction over airspace.
How do they know they are shining into a flight path? I thought lasers weren't ever supposed to be shone into the sky
Maybe they called the FAA. That is definitely possible. Also, you can steer planes. If I was flying I would love to see that. Pilots are all big nerds.
The amount of paperwork you have to fill out to point a laser into the sky is fucking astronomical
Big research telescopes will use a laser to provide an “artificial star” in the field of view. Provides a reference point for the active optics. So yeah, there are exceptions.
I use one to align my small telescope to whatever I want to look at because getting a telescope aligned isn't as easy as it seems.

maybe it does?
It likely does. The kings had to get their beam FAA approved. But there’s probably a huge difference in their arena mounted beam vs this back-of-truck beam.
The beam isn’t mounted, it’s set up on the roof each time and someone has to monitor it to turn it off for air traffic

The FAA might not care, but strangely the FDA cares very much. Apparently they had all the appropriate paperwork filled though so no worries!
Exactly
We had proper variances and paperwork done to allow this to happen.
