The fines are not enough! Serious JAIL time needs to be applied to anyone caught Lasing an aircraft.

Police Officers are like any other group; Some are Bad & Some (most) are Good. Remember it only takes a few A$$holes to ruin the Apple Orchard.

Agreed... if someone is actually lasing an aircraft, or a plane, or even a person for that matter. Depending on the severity/reasons/whatever a short stay in jail would do the trick.

Serious jail time for a 15 year old kid who probably has no clue what he is doing... too much, I'm all for punishment, but unless lives are ruined there is no reason to ruin a kids life either. A @$$hole adult... that's a whole other situation.

Unfortunately your analogy is a tad flawed... it's more like a section of the orchard. I agree with the sentiment though.

Hm... well, I could devise an experiment to help us roughly determine visibility of the beam from the ground.... But I will do some searches first.

Interesting, but that won't help.

I suppose we could just test it in the field - one person shine various power green lasers up into the sky in a line. Then have a person drive away and record how far away they were when each beam faded. We could then determine a working formula for power vs. visibility at a distance (assuming each beam is shot perpendicular to the ground). Further, then using that very useful calculator, we could work it out for other wavelengths, too.

And how you going to duplicate :different types of clouds, fog and other natural obstacles found in higher atmosphere ;)

Unless your talking about a situation with lots of particulate in the air(dense fog, etc) then beam visibility is going to be highly Dependant on viewing angle in relation to the beam. Even a 2W 445 shining straight up in relatively clear air is going to be invisible when you get 20' or so away from it.

Even with particulate scattering, most photons continue on along relatively the same axis as the beam, or get reflected back along it back towards the source. The closer you get to 90 degrees off axis viewing, the less beam visibility there will be.

Hmm. Well then. But my home city is perfect for this test (never cloudy, air is extraordinarily clear). But I think qume is right here.

Yup... I was actually thinking the same thing. An actual real world experiment would be refreshing:D

All that's needed are people looking into the sky at say a quarter mile, half mile, mile, two mile, five mile and 10 mile distance. Maybe just 5 miles.

That would at least give us a starting baseline.

Yup, that's exactly what I'm going to do. I kind of want to do the reverse though.... hand a laser to a friend... and I start walking away.

I think you'll be surprised just how close you won't be able to see the 445nm beam when your viewing it off axis. Even at 2W it's not an extremely high visible wavelength.

A high power green would be able to be noticed from farther away.

I would think that 445 would be actually pretty decent because of the night-vision color vision change and the fact that it scatters more in the sky due to Rayleigh scattering.

Well, I want to try out the experiment with a 400mW green, a 1.1W 445, 800mW 405, a ~280mW 650, and maybe couple more lower power greens.

As for trusting people with lasers... yeah I'm very paranoid, some of my friends I absolutely never allow to handle a laser... one idiot while drunk by accident manager to hit me in the eye with a 50mW green. fortunately about 15-20mW of that is more diffuse IR, it was an off angle, and I was in a bright room... but even so wouldn't surprise me to learn I have a tiny bit of damage from that. So since than I'm super paranoid about who touches my lasers.

@qumefox - I'm definitely looking forward to being surprised:beer:
