Im thinking 1 mile? Not a bad price 2 units $200/each. Its point to point if its private. Be kinda of cool to setup with a friend! It says its water proof but I would enclose it just to be on the safe side.

Any worries about blinding each other. You can't trust those "frikin' laser beams!" lol

Seems pretty cool. Too bad a I can't think of a use for it for me to justify the price.

these aren't new by any means, ive seen them in magizines a couple years ago.

These are infrared, so unless you stare into it, at this power levels there should not be much of a problem. Unless you are one of the night animals. then you are screwed.

NO they can harm your eyes or the birds. I learned about this in my CET class. those big building in downtown uses this technology.

This is a high energy laser, it doesn't matter if the energy is in the visible light spectrum or not. you shoot that puppy into your eyes and bad things will happen.

We use a much beefier version of this at my college. The housing network attatches to a couple classrooms that we have about a half(maybe quarter) mile away. We couldnt run cable because ther parking lot is not our propertie, so unless we rented a t1 line this was our only option. It works well. Every once in a while we have to re-adjust it and sometimes the thing just turns itself off. The bandwidth is suprisingly not all that great. Our laser was expensive as hell, and for double to the price, you double the bandwidth. I figured a laser was a laser, but I was wrong. The hardware at the opposite ends is what limits your bandwidth. I believe ours only runs 100 megabits.

I got to play around with 2W CO2 laser before (that would be infrared)...
So I really didn't go into detail in what I was saying since i am lazy, but basically you will feel the laser before anything, as in, your skin will feel the heat and you will hopefully jump away. If it does heat your eye, you will feel that too but the first damage will happen on the outer layers, of the eye, not the lens and definitely not the receptops. Cornea will take most of the damage and that is slightly better than damaging lens or the receptors. Due to the optical qualities of the cornea and lens, infrared light, laser or otherwise, will for the most part be blocked from entering the eye.
