Very cool. I want to say the Berlin show used about 25W total. Too bad I'm half way across the country because that'd be very cool to see.

Edit: seems I was off by a bit. KGB listed the specs from the website (which is no longer there sadly). It used just under 91W total. I'm guessing they used Kr-Ar lasers.

There are some pics in there still but only the video in the OP still works.



"Technical background information:


Divergence from all beams are below 0,4mrad and maximum of 3mm beam-diameter
for the green line, and below 2mm for all other colours. No extra
collimation optics are used to keep the rainbow looking more real with
slightly overlapping colors after 6km distance.


colour wavelength power

red 628nm 15,8W pure laser power
orange 628nm/532nm mixed 15,0W pure laser power
yellow 628nm/532nm mixed 19,5W pure laser power
green 532nm 10,5W pure laser power
cyan 457-514nm mixed 24,5W pure laser power
blue 457-488nm mixed 12,0W pure laser power
darkblue 445nm 8,5W pure laser power

All laser sources are pure single line resonators, no common diode-arrays or
OPS-arrays are used."
