Good warning. Police helicopters are still fair game though, right?
I know that's tongue-in-cheek, but seriously - most helicopters have a lot of glasswork up front, often in big continuous mouldings with a couple of layers for good measure. Laser light bounced into that at night can be scattered by scratches and bubbles in the glass, making the entire thing appear to glow. Not good. Not good at all! It used to be great fun shining it in the tiny break in the neghbours curtains, used to drive them bonkers!
B&Q flashlight, world away from these things.

When the beam hits something shiny, it disperses with great intensity in all directions.
Shining these at planes, helicopters or even vehicles would be a seriously dumb, brain-dead and monumentally stupid thing to do!!

I recieved mine a few days ago.
Well put together chunky piece of kit (200mw Red). Lights matches from about a meter within 2-3 seconds. But in order to do that you have to twiddle the lens to focus the spot as small as possible. Not tried further. Burns the match shaft with little problem but won't touch simple white paper.
Will only heat up stuff which is opaque (obviously) so won't burn through CD cases and the like.
I notice on the box that it comes from Hong Kong, not America. Also notice they do 500mw red lasers. I'm sorely tempted to find out the company on ebay and see the price of the 500mw version.

Not really worth trying out for obvious reasons but the idea that you could focus a beam around the underneath of an airplane, into the cockpit and burn a hole in the pilots eye is just beyond any sort of reason to my mind. The scatter caused by passing through any sort of perspex would render the beam powerless to do anything.
Annoying, juvenile and worth a kick up the arse for annoying someone doing a job yes, death sentence for murder, bit hysterical. Pilot claiming he'd been blinded by said action, worthy of investigation of pilot rather than scrote I would have thought.

Yip really funny, laughing my socks off at the thought of this little bit of high spirited fun.

I think the problem is with the sensitive infra red equipment scanning the ground for heat signatures. If hit with a dinner plate sized beam they would effectively show a complete white out, likely interfering with the use, and possibly damaging the sensitive sensors used in the infrared detector.
Certainly gen 1 or 2 night vision equipment would likely be perminently damaged if suddenly exposed to bright light of the sort a laser could muster.
I think the police would go after the holder, not because he'd done something dangerous, but because he'd potentially done something costly, or that he was interfering with the course of justice.

Ordered it from the link on here. Its fun in a physics curiosity kind of way, but loses any ability to heat or burn anything after about four feet. That could simply be a dispersal or focus issue, but no matter how you try to focus, the beam is scattered just by the atmosphere. No matter how well you focus it, it seems to be a dinner plate at a few hundred meters. I could be wrong but even looking directly into the beam at dinner plate size from a few hundred meters away is unlikely to damage your eye. I suggest damage would come from being close enough to an unscattered beam. Maybe collimators or lenses way beyond what the things sold with would improve that aspect but ?why.

Depending on the power of the laser it is more than possible to temporarily blind or dazzle someone at quite some distnace with these lasers- as you seem to have found compared to others the quality of the optics isn't great and so some will focus etc better than others. The same also applies to the power output. At close range 5mW will do damage as a train driver will testify (as well as a number of pilots). Perspex is quite optically transparent and will often deflect the beam bending it inside the cabin of a plane etc.
While a big search light may have a lot more power the fact that a laser has a much smaller beam size (even if it is dinner plate sized a few hundred meters off) and that all the 'waves' are in phase (ie same way round ) and the same size makes the laser effective at heating things up etc.
If you really want to try shining it into a plane or something please try this first: find a friend and get them to shine it at you sat in your car from some distance off. Your reaction will be exactly the same as your targets.

Except that having the perspex glow in the colour of your chosen laser kinda limits your ability to see through it - it's not really about the pilot having a hole burned in his eyes! http://findarticles.com/p/articles/mi_qa3957/is_20...
Canopy glow from low powered IR lasers is a known pain-in-the-arse for pilots flying with NVGs - not because of any damage to the NVGs, but simply because of the glow of the canopy. It's fair to assume high powered visible lasers will have a similar effect on pilots flying without the specops goggles . I've never been in that situation, but I have seen the effects on a scratched up Lexan panel in a darkened room - a pretty rough approximation, but still...

Received my 200mv Laser red yesterday after ordering it on the 2nd sept...
Ordered my green one on the 26th of August and still not recieved it, atleast the tracking report now says its has been shipped..Want.

MoJo.
OK, after reading this thread, and seeing as I'm in a spendinglotsofmoneyonstuffidontneed frenzy I have just ordered:

Awesome. Should help fill this...
Man stuff. I love it.

I have one of these (50mW green) and it's excellent. You can see the beam in daylight much better than the red one below. http://www.dealextreme.com/details.dx/sku.2390
That'll do for me, just ordered one TA!

When you get yours, try shining it at night and then spray anti-persperant along the beam
