Trip into the past the Las Vegas Hilton 532nm laser
I'll put the picture up. I do believe this is the only picture of the laser apature, my finger is NOT in the beam, it was the tech who ran it. to get this I had to iris the camera all the way down, and had no idea what I was taking with the goggles we had on. Looked like ones left over from the 50's big heavy n COOL! but you do get to at least see the apature it was almost 6 inches across BEFORE divergence. When it hit the mountain just past Primm Nevada it was the size of two football fields and nearly 40 miles away! F'n AWESOME just to look at!!!!... all gone now youngsters... But here is a peek
This is a scan so forgive the colors... but I do believe this is the only picture of it.
I also found someone elses discription of it here..

I was halfway through the desert when the lasers took hold. Miles from Las Vegas, driving north, a fat green laser beam shot up from the (ity and swooped over the roof of my rental car. This wasn't your ordinary, razor-thin shaft of emerald green light twinkling in the night. This was a big, broad, landing strip of light large enough to accommodate multi-engine aircraft. It pulled me into town, toward the ground zero of Las Vegas. I saw it clearly. I followed it. I was dazzled.
WORLDS LARGEST DISPLAY
My first stop is the Las Vegas Hilton, host to what Laser Fantasy International says is the world's most powerful laser display installation. From my hotel, just a few blocks from the Hilton, the display is hard to miss. I see a beam lying low over the city from this angle, splitting the night air like the center line down a highway. The lasers originate in a fountain at the Hilton's main entrance.
The display is powered by four 40-watt YAG lasers that funne; theirl light through 16 remote fiber-fed scanner pairs. It operates in two modes: a five-minute "beam and light ballet" that projects beams into the atmosphere, and a static mode that projects four beams on a nearly flat trajectory low over the Las Vegas skyline. I like the static mode best-the beams are more visible because they're closer to the ground, close enough to illuminate palm trees with an eerie YAG-green glow.
I watch the beams nearly alone in front of the Hilton. I'm told the Hilton opted for the big beam installation because they're a block or two off the main strip, and wanted a high-profile landmark to make themselves known. The lasers certainly grabbed my attention from blocks (and miles) away, but they didn't seem as impressive at closer range, perhaps because of the high ambient light levels and less direct sight lines. But maybe that's the point-when I'm at the Hilton, they probably want me inside playing the slots, not ogling multiple YAG outputs.
