Hi all. 

Sometime in 2023 we plan to hold a Circassian dance troupe in my friends local village (Chechnya). The dance area will be approx 1x1 miles sq, and we’ve budgeted approx $3-4M USD for setup.

We need to accommodate some bespoke 10 megawatt “SilverStream” galvo laser projectors (no point Googling, they are being custom made - we don’t yet have the full specs yet except that we are using 5 of them and they’re in need of water cooling) - they will be strategically located on the sides of surrounding mountains on anchored gantry frames, in a star formation, pointed downward to the valley floor where the performance area will be.

We’ve been provisionally told that it would be a wise idea to have a lake or stream nearby from which to source the cooling water, it will need quite a lot I’d think 🤔 😂

Does anyone here know anything about this stuff? We have a contractor building them when we’ve finalised plans, but I’d like to know if there’s anything we should plan for in advance. The contractor is offline and on job somewhere else right now, so unavailable to ask.

PS: throw your “rules” out of the window if you’ve got commentary re legality based on Western rules. This is Чечня, not rural Iowa.

Many thanks


For the slightly behind:

“/S”

Don't thank me yet,
That forum is where all the high end laser show guys hang out but I suspect they will have 'serious questions' when you mention 10 megawatt entertainment lasers.

Fine. I appreciate the pointer. If they are helpful and efficient we’re gonna do fab. This isn’t one of those toy laser pointer obsessives’ forums is it?

I've not used the forum in many years. It's for professional people in the laser industry, not laser toys.
They are super helpful but they don't give out dangerous laser information to random people. They need to trust you.

First up have plenty of back up twirlies available as there likely to instantaneously combust if they dance in   the beams,also maybe  get a block booking for the local eye hospital.And best to ban cameras to avoid punters trying to claim against you when they try and take photos of the pretty laser beams

“Claim”? 🤣 all the best with that. You do understand fully where the location is, right?

The laser rigs will be up verrrrrrrry high (the height is needed for divergence of the beans to soften it slightly, and to ensure no eye-level horizontal beams - and of course a higher altitude = cooler rigs)

Water cooling is suspicious these days unless your using something very dangerous from the past. We'll handle this on the Lexicon 

BtW, since your describing peak power 100,000 times hotter then anything  we pros have ever used, you might want to check your numbers.

I'm confused.  If you search for it (that laser name thingie), I seem to find it, on this very forum.

But it seems to be claiming 5mW = 5 milliwatts, NOT 10 megawatts.

Big difference.

Link here:

https://www.eevblog.com/forum/projects/scavenging-a-galvo-laser-projector/

The one that's in it is 5 mW.

10 megawatt = Shoot down ballistic missiles.
10 milliwatt = Play with cat.

Thanks Steve. We have no doubt it’s megawatts. Do you know how large 2 square miles is? I’m sure you do. I don’t need to check the numbers, our supplier is very competent and we know they’re not in the business of making errors when having such events.

It’s NOT a commercial unit, it’s a bespoke rig which has been commissioned for the event. I know it’s not milliwatts for certain. These lasers have to penetrate potential low cloud cover/mist at night, and still have plenty of juice left to reach down a few thousand feet. This is no game. We are in Russia, not toytown. They don’t mess about and money is no object. This is a huge event. Googling it won’t get a thing, these are early stages.

Also, does anyone know how to fix a flux capacitor? I dialed my Tardis to jump forward to April 1st 2023, but I must’ve blown a fuse somehow.

Merry Christmas to you all, Happy new year and Happy (future) April fools 2023!

Forgive me, I had a boring Christmas. 😁

Many thanks.

Laser Ssfdty Rules around the World have been harmonized lately. After the Bulgarian incident the former CIS block tightened their rules  as well.

Not much difference any more, IEC applies in Europe.

Check your laser is not a pulsed laser.  (pulsed lasers have super high peak output power but that pulse is super short. They may fire a lot of pulses per second and appear to be a constant beam when they are not.) A pulsed laser might have a very high peak power but a much lower total power.

One key thing to understand is to NEVER use a pulsed laser to do anything near people especially audience scanning.
This has happened before and caused a lot of eye damage. Galvo's don't reduce power for pulsed lasers. The pulse is so short the galvo might as well be stationary.

My flux capacitor broke. I have no knowledge of this thread. I can see it exists but it must’ve happened during the fusing of the supply, in my attempt to jump forward 5 months 😛

Since “Our Dave” is mad on Delorians and “BTTF” movies, I reckoned he’d get it pretty fast. Maybe a bit too dry? Whoops.

We have no doubt it’s megawatts.

If you divide your laser power by around 300 = 33 kilowatts = The laser power level used by the US military lasers, anti-threat system, which can attack small ships, drones and things.

See here:
https://en.wikipedia.org/wiki/AN/SEQ-3_Laser_Weapon_System

So, you are proposing something around 300 times stronger, than something which can attack small ships?

The exact level of power the LaWS will use is unknown but estimated between 15–50 kW for engaging small aircraft and high-speed boats.

10 megawatt = Shoot down ballistic missiles.
10 milliwatt = Play with cat.

Dude, 10mW = blind the cat, and yourself. 1-3mW is what you get in commercial (legal) laser pointers, and even those need to be treated with respect.
