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

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.

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?


--- Quote ---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.
