An 11.5 W 532 for any big spenders out there...;)

I wouldn't call waving a 3 foot "match" in the beam being safe.....but whatever. His eyes, not mine.

If that laser is pointed at your head your brain is cooked !

What I want to know is the roof catching on fire?

Wait wait wait....... no glasses ?

To the best of my knowledge Pat (Laserman532) does not even own glasses. If one is not only a professional, but most importantly very careful and attentive they can get away with that when using fixed lasers where the beam path is known and does not change. It is NOT recommended though, as most people would agree that it's better to be safe than sorry. Accidents can happen in such a short amount of time that reaction to avoid a direct hit is impossible, ESPECIALLY with hobbyist lasers which tend to be small and very often handheld or portable.

Laserman532 was the first person to use those big green Laserscope surgical lasers for laser shows quite a few years ago. They were and remain a big hit with audiences due to the incredible visibility of the beam. Scanned beam effects can often be seen for many miles when used outdoors on clear nights.

EDIT: didn't see the previous post from Sigurthr..

Still doesn't answer my question... What about the poor roof?

And do they make laser goggles for 41W of 532? :eg:

Not that would take a sustained hit, but they do make goggles that will protect you long enough to move out of the way.

As far as the roof goes I think he said it was terminated on a steel support beam.

The laser on ebay is flashlamp pumped and pulsed at up 10Hz, so it would be more of a ticktickticktick sound with pulses bright enough to pop retinas from even diffused reflections

A quick run with the calculator says that with a 2.3 joule pulse of 4-8 nanoseconds would result in a peak power during the pulse of 383 MEGAWATTS, and the laser can fire shots with that energy five times per second.

Only $56,000.00 :crackup: :crackup: :crackup: :crackup: :crackup:

I guess that means I can count myself out.

Also, why on Earth was the guy in the pictures not wearing goggles?
