Video of 8 watt laser!

If your going to do it, do it right. This has been done in decades past, I'm not a fan of non scanning beams, but here is who he's copying.

Figure out the funding to do this in both New York and Berlin, the attached video is Yvette Mattern, which is where this guy got the idea. She got major funding to do this for a few nights in both cities last year. She's a social animal, who was smart and hired techies in both cities to get results. Her Dad worked for the FAA, and pulled strings to get her into NY Airspace legally.

Besides, German regs prohibit fixed outdoor shows in most cases, as does much of the rest of Europe. And yes, this is a show, in airspace, by legal definition, not art.

I'm not too impressed with 8 watts, what I used to work on had two largeframe argons and a large frame krypton, so about 60 watts nightly, all summer. With 4 scan heads and about 30 beam positions.

Those are some very impressive lasers in the video! Are they all argons and kryptons?

Naah, they are usually DPSS and cavities ..... look at this "rainbow" video, around 2,30 time, there's a list of the lasers that they have used.

I see, thanks for explaining that.

looks like a green spotlight. could have been better IMO.

It would look like a white house with a green dot on it for about half a second... Then it would look like a white house with a dead guy laying in the yard with about 50 bullet holes in him.

Needs better divergence (<.1mrad?). fail

Actually,

Argon blues, a krypton red, a DPSS red, a DPSS green and a sum frequency mixing yellow, not red and green with dichros, that is a "yellow" research laser for sodium guide stars.

try pulsed 1380 mixed with pulsed 1064 and ran into a nonlinear crystal to get 568 or so, they call it mellow yellow.

A lot of research lasers as well as show lasers were borrowed to make that array. Big funding $$$$ involved for such rentals.

There is a picture of all these lasers under plastic tarps in snow/rain for that shot.
