Strongest green laser?

350 watts at 515nm? Yeah right. If you want a powerful green, take a look at this:

Its probatly not new for you guys, but i just came across this monster: http://www.lightline.de/deutsch/produkte/download/nova400.pdf

350 watts green laserlight... want to see that in live. They claim it to be the strongest lightlaser in the world.

Little video to it: Licht über Osnabrück-Stärkster Laser der Welt? - YouTube

That's the most green I've ever seen or heard about.. 350W is ridiculous. I can only imagine what that looks like.

@Soren: The Laserscope cavity in that diagram is only good for up to 40-60W of 532nm. It is a pulsed system, so the peak power is FAR higher, but so is the system in the OP here. The 350W would be average power.

Somehow I doubt that is the current "Hottest" green. It may just be the "hottest" civillian green in Germany. LLNL published 350 watts of green using hydrothermal KTP more then 10 years ago. I imagine they have a bit more now. :eg:

You don't "look" at systems containing that amount of visible power, except when your taking publicity photos. The scattered light is a hazard at some point. If that is 1200 watts on such a foggy night, then they need a better camera.

Wow definitely not that high powered then! :crackup: Only 40 - 60 W...that would still be unbelieveable!

Yeah I was wondering that too. +350 W of 532 and you can barely see the beam :thinking:

It depends on the camera setting. You can make a 5mW laser looks like a 5000mW hotshot and vice versa.

Yeah thanks Blord! I do realise that, but I was under the impression the photos were taken professionally. Guess they werent...
Anyway its hard to mess up the exposure, even with a point and shoot, with a beam of that power. If the exposure of the background (at night) turned out ok it would have had to have been..high iso, fast lens, longer exposure or a mix of all the above. If the exposure was longer, the beam would have stood out. Heck a 5 mW green would have stood out!;)

Lol.. 40-60W is impressive, I meant compared to 350W. This system would eat a Laserscope for lunch. It would eat any visible laser that I've ever seen or heard about for lunch and since it's green, which is near the peak of human vision sensitivity, I'm sure it's positively blinding up close and breathtaking against a cityscape or something like that. The video in the OP is disappointing to say the least..

I did notice the term "150km" in the description, but due to translation errors I can't tell if they mean that the beam is visible out to 150km or that the video is shot from a distance of 150km. If the latter it's damned impressive..

they say that the beam reaches up to 150km into the stratosphere.
Thay also say that they use several kw infrared to get some houndred watts of green light. for the test you see in the video, they put four units together, making 1600w of green laserlight. world record as they say.

i think the military doesnt use visible lasers that much. they are more into strong infrared lasers (as the airborne one for destroying rockets).

There were two distance references in the text:
kann bis zu 150 Kilometer weit in den Himmel leuchten
Click to expand...
Which means goes up 150 Km into the sky. The other might explain it though:

Die Laser-Tests waren bei klarem Himmel viele Kilometer weit zu sehen

The tests were visible from several Km's. So maybe as you suggested, the pic was taken from a far? :beer:

How about a forum buy? I could ask them for a special deal and we do a good review for them... lets say 500€? Who is in? :D

LOL, if that 350Watt beam hits your eyes, you loose the head. :D

For the most part. The Chinese government does however have a "lasergun" designed for blinding pilots and non-lethal purposes.
