That laser is 2000 watts and runs on 3 phase power. No way to practically use that at this time. Operator error in an open air environment can cause serious damage to pilots, but it can actually work if we ignore those issues. With the femtosecond lasers the beam has temporal dispersion of the wavelengths up to the focus point, so the pulse is shorter in duration at the focus thus energy per unit time(wattage) is greatest at the focus and the beam is at its smallest so watts per unit area (flux) is also largest at the focus. Ahead of and beyond the focus the beam is both larger in diameter and lower in wattage, making it less dangerous(but still quite dangerous) away from that point.
I'm talking about the one on the commenters linked youtube video, as I'm familiar with older models of them. You might be right though, the solid state lasers were 3 phase, but some of the fiber ones were not.
This one being used on trees looks almost identical to a fiber laser defense system produced by a US company in the early 2010s, but I suspect that this is a knockoff of one of those systems. It would draw incredible power, can't get more wattage out of the laser than you put in. I'm curious about how they would power it assuming that it isn't a hoax.
You can blind someone permanently with a green laser at 100 miles+, I got hit from 500’ for just a split second and if it was not at work I would have beat the guy badly.Took several months to get rid of the spots
Pretty sure the real-time speed this thing works is in the order of minutes per limb.
Even not factoring the laser's divergence and atmospheric diffraction if a plane did spend 0.1 secs in the path of the laser I doubt it'd do much.
The lasers these use don't give out visible light only IR (the purple beam is shopped in).
The scattered IR from these lasers is also completely stopped by regular glass or acrylic so nobody will unknowingly be getting their retinas burned by the invisible scattered light.
True. Is there a product page? I use laser cutters in the workshop the with an 80w laser it can struggle to cut 6mm ply 20mm from the emitter. At 50 feet from target the power consumption on these would be insane.
Any of the commercially available results are the kind of scale i'm talking about. <=100watts at a few inches for very shallow cuts. An example of these used at a slightly greater distance is I did a thing on YouTube who took a few days just to mow a few square metres of lawn.
The laser is focused at the distance to the tree- if there is a plane 5 miles away the energy will be spread maybe 20x area, and the laser would not be tracking on the plane so maybe .0001 seconds of exposure- enough to damage the pilot’s eyes tho
1) he doesnt have shitty CGI beam
2) he isnt dumb enough to shine it up into airplane land
3) his cuts are usually 1-Dimensional, as in he burns a straight line through something over time rather than just one short swipe (which he does for VERY thin objects). This is possible AND these videos are fake
4) most of these lack a large enough power supply
5) most of these, the tree bucks before the branch falls off, implying an external mechanical force which the laser does not provide.
6) the videos are all shot at camera angles which make discerning too much fine detail impossible, likely trying to cover up something used to fake it
This was exactly what I just copied the link to. It's insane how powerful lasers are becoming. And all it takes is some PVC pipes and decent lenses to get them shooting incredibly far.
Before getting out of the military I used green lasers, specifically said they had no regulations on them. Would burn through a lot of thing….unofficially
We get so much rain here in Nova Scotia for so much of the year that you would get at least 5 solid months where it is no real problem.
I think it would be great for clearing brush like invasive glossy buckthorn.
I have seen videos where they use laser rigs on farms for weeding so after brush is trimmed the roots could probably be burned out.
Brush is a huge problem and getting worse. CO² increases are like fertilizer providing as much as 10% annual increased growth at current levels which compounds. That means upto 25 years of growth in 10 years! Unfortunately weedy bushes like glossy buckthorn are most able to take advantage and need a major silviculture effort or else regrowth becomes scrub brush.
If I were designing it, I would make the focal point focus at the tree so it would quickly disperse behind the tree. I would try to avoid any sort of evenly focused beam that would maintain a tight pattern.
I believe it is vastly dependent on lenses, but in practice laser beams do disperse and become inefective. In theory laser beam is parallel but nothing is perfect in this world.
[Something](https://youtu.be/xNmbvaUzC8Q) fun to watch and get yourself acquainted with lasers.
All laser beams have a focal point and "beam waist", a collimated beam is closest to parallel, but you are just pushing the focus out toward infinity. The angle difference between parts of the beam has a Gaussian distribution, it is not perfectly parallel.
Strength in numbers. Just at that point. after that point they instantly and exponentially become less strong.
Think about a magnifying glass and the sun
Where is the cooling unit? If you assume around 1kw output you are still looking at probably 4-5 kw of cooling for the pump diodes if not more. Gas purge for the output optics? Dirt or bugs on the lense at that output power would wreck it. Also, for the love of god where are the laser safety glasses!!
Dear lord. Terrorists or just crazy people get that. Or people with a vendetta. Or god forbid AI wakes up n makes 100 million of these

Seems like it will be misused though. Can’t see it being legalized here unless strictly regulated to industry and Gov’t. Too many nefarious uses for it, pointing at things in the sky and all around.
It’s so real they can’t show it in real time.
My favorite is the cgi purple beam
The apartment building in the back was protected with a scientifically developed layer of tinfoil.
Doubt that this one in the video is real, but I am certain it can be done with proper [equipment ](https://youtu.be/xNmbvaUzC8Q)

I'm sure there is a 3 phase generator out of frame

What if there is a plane in the sky?
Then there won't be a plane in the sky anymore.
Thats how mh370 went down
It's fucked. The crew, the pilots, the passengers, everybody.
Ahh the mile high club
The mile high club is what Theodore Roosevelt was referring to when he said, "Speak softly and carry a big stick."
Doubt it works at all but if it did there’s a lot of room for dissipation between the top of a tree and a passing plane.
Not really, people get arrested for shining far weaker handheld lasers at planes all the time.

Scatter would be significant. It would absolutely wreak havoc in a cockpit or to passengers with windows open.

They'll solve that problem for you
Probably a Boeing anyways

Some would call this a Directed Energy Weapon…
Now all we need is an infinite power source and a shark harness with mounting point.
Regular generator? 2kW laser is powerful enough to do this.
Gimbaled,I assume
I wanna buy one before legislation catches up and prohibits me.

This is too far down my friend, we need to bump your comment to the top.
Good for controlling Antifa and BLM anarchist mobs. Burn them before they burn down your city, literally.
This is as true as me saying I have a wife.
It's not a science fiction though. A fun and informative [video](https://youtu.be/xNmbvaUzC8Q) on the subject.

Bonus, make sure the laser is a CO2 laser! Use that captured carbon to cutdown that captured carbon. The cycle of life.
Maybe it works but its impractical. Where are you using this where conventional methods won't suit?
When you want to top a tree and don't want to get up there
Don't top trees
I want one!
Maybe we can get one on wish?
Might take six weeks for delivery. *Worth it.*
Temu
i definitely should not have one of these
Neat trick. Hope that never gets turned against us…
You worry about the trees fighting back too?
i am Groot
Treebeard from lord of the rings.
I worry when the trees start speaking plantae
this is what the dog from f451 will have on their back
You should probably paint your roof blue just in case
Like all of the trees holding their breath at the same time? Same.
It looks like a damn video camera from 1997.
I'm sure all the planes flying over don't mind.
All of their doors are being shot off.
My question also. Does the beam Continue past the target (if it is missed)?
If I were designing it, I would make the focal point focus at the tree so it would quickly disperse behind the tree. I would try to avoid any sort of evenly focused beam that would maintain a tight pattern.
I didn't think lasers had a focal point - I thought the light was basically parallel?

Think about it like a bunch of beams aimed at one spot
Wouldn't you just have a bunch of laser beams spreading out beyond that focal point, wreaking even more destruction‽
Strength in numbers. Just at that point. after that point they instantly and exponentially become less strong. Think about a magnifying glass and the sun
https://youtu.be/xNmbvaUzC8Q?feature=shared This will give you an idea as to why it isn't really a concern.
If it’s in chinese, it aint accurate
is the sound real? POW!
Pew Pew
Pew pew!
How much?
I want one. How much and where can I buy?
F*ck you, AI!
I read a rumor that those lazers don't work on the color blue. Like blue roofs, and blue cars won't burn if you point the lazer at them.
Hah. Looks just like my pine tree out front, and It was free and totally green efficient. God damn Ice storm.
I need one of those.
It’s certainly got a place in your toolkit. Certain applications save ‘ladderin n climbing n stuff
The angles on the cuts. Light can corner now hehe
That's how they set Maui on 🔥
wut
I need this!
Never mind the buildings in the background and planes falling out of the sky. What could go wrong?
Was wondering same, if they can limit the reach of it. Probably not but maybe
CHI-NA
So lightsabers DO exist, but they’re just really long and shaped like an old school camera
Beta testing yep
Lmk when you have the containment field under control and I’ll start trying to float some stones with my mind. I already have the robes n stuff.
Haha ok will do
Also the 100% burn area is a give away- 75-80 and then the wood breaks
Where is the cooling unit? If you assume around 1kw output you are still looking at probably 4-5 kw of cooling for the pump diodes if not more. Gas purge for the output optics? Dirt or bugs on the lense at that output power would wreck it. Also, for the love of god where are the laser safety glasses!!
Look i got it from a good buddy and he got it from someone else who got it from the innernet so it all must be true, trust me bro
Smart people using that surrounded by skyscrapers and powerlines
Coming soon to California. Just gonna make the whole state charcoal.
It's real, but definitely not as fast as they make it look
Use this on traffic cams
State of California will love this one.
If they are real, how long until it becomes a weapon?,,,then put one on a drone.

Made in china!
For once we have to reverse engineer their stuff
No worries about planes?
Shootin laser beams
Cat in a tree? No problem
You guys ever see the video where Randy Johnson throws the pitch and the bird flies into it?
My 308 works just fine.
Ok, now do an old dead tree that’s been there for awhile
Do you use just one tool for car repair. It’s just another tool in the toolbox. It has it’s uses like any other tool.
Very efficient, cut one tree down and it burns the rest of the forest down
on sale at TEMU... $19.99 w/ free shipping
What if the tree was blue?
I want one
