I just HAD to share this with you guys, I'm still snickering as I type this ... Last night was a nice semi-foggy Wisconsin evening, and as I pulled up to the club I play at on Wednesdays, from across the street maybe 1/4 mile away BAM - my fiancee and I get hit with a greenie beam! Kinda surprising, made me realize how it spooks the hell outta people when I do that sort of thing, but hey no big deal, EXCEPT...

As we're unloading equipment, the damn thing keeps hitting us, and other patrons, and cars on the road, and pretty much everything that moved in that little part of our town ... Well, at that point I knew it had to be kids or someone that deserved a lesson, so we grabbed my laser case out of the truck and grabbed the club owner and manager and boogied up onto the roof deck for a nice, high vantage point...Where we quietly sat and waited for the "greenie bandit" to strike again (which they soon did...)

BAM! BAMBAMBAMBAAAAAM!!! Between the Hercules 350, the (2) greens (200 and 50mW respectively), the 3 Dildas, and the 6X Bluray beams that we simultaneously sent raining down on the culprits lair from the sky, somewhere a distinct point was silently yet brightly conveyed, and the assault from down the road stopped quite abruptly with a really, REALLY loud "yelp" from the general direction of the opposition ;D ;D

Post Note: Halfway through the show, my buddy Chad came up to the booth and was laughing his ass off, turns out he was at his sisters place (the house down the road) and was letting the nephew and niece play with the 50mW I gave him a few months ago with strict rules to NOT take it outside of the garage, shine it at anyone or anything, etc ... Well evidently the yelp came from his sister who had just gone out to yell at the kids and ended up taking the brunt of our return attack, spilling her drink in the process and quite possibly shortening her life just a bit!

The kids stopped crying in about 20 minutes, from what I was told ....

Isn't it kinda dangerous to point a 350mW green laser at someone from 1/4 miles? :-/

Whoa, there - I made it abundantly clear to everyone involved not to actually hit anyone with the beams, but to shoot over their heads (shoulda pointed that out in the story, sorry!) ...

NO it isn't. By that point the beams have spread out to the point that even if they did somehow make it into direct contact with a retina, the power level is quite low. Not harmful at all. I understand the need for laser safety, don't get me wrong, but this is going a little overboard methinks..

Ahh okay, in that case I take it back :)

Agreed. Very funny story and I think your point was well made, but perhaps the Hercules should have stayed in the case for this particular engagement.

On the other hand, I think those kids will think twice about lasing the general public again.

EDIT: Just read your reply, so that's a good thing but it's still a little risky considering you have a >500mW peak on that thing.

Even at 500mW, from more than 1300 feet away the spot size will be large enough that the amount of power that hits a persons retina would be negligible. You have to remember that the 500mW of power is distributed across the entire spot, and also will have been attenuated (very slightly) by the atmosphere. If the spot is a foot across at 1300 feet (which would require extremely good divergence figures) then the amount of light that makes it through a pupil less than a quarter of an inch across will but a tiny fraction of the full power being distributed across the 1ft diameter circle.

Assuming:

range = 396m (1300')
beam divergence = 1.0 mrad
power = 500mW
diameter of pupil = 5mm

Then the amount of power entering the eye would be about 0.076 mW.

So, you're right, but it still doesn't mean I have to like the idea of pointing a Hercules at people.

That is true. Generally speaking it's never a good idea to point high-powered lasers at people. In this case, however, the danger is negligible.

In Arkansas, replace the word "laseer" with "gun" and "mw" with various calibers, such as ".22", "410" and "9mm" and you'd have a pretty fair description of a Littlerock Saturday night.
