content: 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 thanksFor the slightly behind:“/S”

content: 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

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)

content: 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/Quote from: Kevman on July 11, 2020, 12:23:08 am

content: Quote from: LaserSteve on December 26, 2022, 04:35:41 amThanks 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.

content: 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.

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.

content: Quote from: eti on December 26, 2022, 04:57:09 amIf 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_SystemSo, you are proposing something around 300 times stronger, than something which can attack small ships?Quote

I was just using it as an example of the difference between mega and milli.Can you do some lasting damage with 10mW, sure, but you'd have to be doing something really stupid or doing it on purpose.The reason the old 5mW pointers were limited to 1-3mW was because a small number of stupid kids were intentionally shinning it into there eyes directly and on purpose.

content: Quote from: Infraviolet on December 28, 2022, 11:05:37 pmI think the OP, got worried that their original thread might get noticed by the moderation team, and get them into trouble. So they changed things, such as the title, to try and hide the evidence, of their activities.10 TW, is approximately 20 times the entire electricity power consumption, of all of America, at any given time.Source:https://www.huffpost.com/entry/laser-record-national-ignition-facility-beam_n_1688757The OPs laser will probably be fine, as long it doesn't operate for longer than a few picoseconds, at a time.

I’m a grown man not a child - I know this forum sometimes breeds an air of childishness and back-biting, but there’s nothing “hidden” here. The day I’m “scared” of something online would be a fine day indeed.People take things too seriously. I’ve got a terawatt laser pen for anyone wanting to play with me. 🤪😂
