They definitely can. I'm sure a doctor will be along soon enough, but I've known people that have received scarring. Some crappy red pointer won't do it, but there are plenty of green lasers of dubious legality out there that can. And that's not even getting into the realm of military application.

Alereon posted:There are vendors selling lasers that are illegally powerful and consumers modifying their lasers to illegal power levels, but the idea that <5mw lasers (even green) can cause eye injuries to pilots (versus just being unsafe because they can interfere and distract at a critical phase of flight) seems like an urban legend. Last time I checked, in the US, >5mw lasers simply have to be marketed as "laser modules," instead of as pointers, and include an interlocking switch (basically two switches that both need to be operated for light,) to be legal. Even that limitation is based on an FDA rule, rather than criminal law, so getting arrested for one would take a serious bug up a rather knowledgable cop's rear end. They're all freaking over. (>5mw lasers, not cops.) I don't know of an incident involving actual injury or damage, but its really something we take seriously. If you ever see someone trying to lase an airplane, call the police immediately. It's loving dumb, and could genuinely hurt someone.

pik_d posted:Did you put it into a ditch because you hit a guy in a parachute though? Does it matter? As I see it once the plane got turned sideways it wasn't really functioning as a plane anymore, just a vehicle that happened to be airborne at the time, basically like my truck as it entered the ditch. Anyways I was just going for a rough comparison to something most people will be more familiar with. The average person immediately thinks big impacts when they think plane crash, where this one as far as the forces involved was a lot more in the range of a small car crash.

Turthfully though, >5mW lasers are stupid easy to obtain. They're all over eBay. Because of import restrictions, none of them will ever mention their power output, or call themselves a "laser pointer", but it just takes a quick bit of Googling to verify the model being sold has a high output. I bought one a few months back to play with and I won't think of using it without the eye protection, let alone point it into the sky. Just pointing it down the street at a stop sign and bouncing it off the retro-reflective material of the stop is enough to dazzle me, in daylight.

Lasers are a huge concern for military pilots. Pack in 24 dudes in the back with lasers on their rifle (both visibile and IR) and then a tail gun on the back (aka gently caress you to -2/3/4) not to mention the other aviation assets you're working with and you have a battle space full of them. Tight control measures help but nothing you can't prevent everything. IR lasers are what scare me most. Night time on goggles you'll see them, maybe. I really can't think of a good reason for a laser other than as a designator or sighting system. gently caress all people who shine them at aircraft in the butt.

It just sucks. Plenty of other programs that he could have gone after that in aggregate would have freed up the money he was looking for. But I can't imagine the hell that would have been politically. Can we agree on never linking to a Gawker site in this thread?

Cheap green lasers are a lot more dangerous than you'd think -- even ones rated at <5mW. The green color is somewhat tricky to get straight out of a semiconductor, so it's usually obtained by chaining together infrared laser diodes and various frequency-modifying crystals. For instance, you might have an 808nm (infrared) diode that pumps a 1064nm (farther infrared) crystal that is then frequency-doubled to 532nm (green light). The catch is that the initial infrared diode has to be several times more powerful than the intended output power, because the optical conversion is inefficient. So your 5 milliwatt green laser might have a 30+ milliwatt infrared diode in behind. Good laser pointers will have strong filters that prevent anything but the green light from escaping out the aperture...but cheap laser pointers often leave that filter out, so that your relatively safe green light is surrounded by an invisible ring of powerful and most-definitely-not-eye-safe infrared light. Because the IR scatter is wide, it can get into your eyes even when you're not looking down the axis of the green marker beam. Then, of course, since you can't see the light you have no blink reflex to protect you from it, and your retina can't feel pain, so the only sign of damage being done is when your vision starts to fade (or, according to the gruesome stories from some laser technicians, you hear and feel a *pop* somewhere inside your head as the intraocular fluid boils)...you can see how something that seems benign can be surprisingly unsafe.
