Hmm. Maybe they can't. Not sure where I got that from. Also, you can't pour perfume in someones eye from a few hundred yards away. Nor could you pour it into the eye of say, a pilot, from the the ground. Also, if said perfume was washed put pretty quickly, it could be avoided. Plus, diffuse radiation of perfume doesn't exist.
You can't blind a pilot from a "few hundred yards" away with this. As far as I can tell you get your laser facts from Master of Orion 2, so maybe you should take a trip to wikipedia or something.
Laser quickly loses intensity because suspended water molecules and other particles get in the way of the light (that's all lasers are, concentrated light. Not radiation), which is why you can see it's path - it's bouncing off particles. To do any kind of damage to a pilot with this you'd have to be hovering about twenty feet away from the window, and the pilot would have to not move his head. Just doing what you instinctively do against light (putting your hand up) would block this deadly attack.
This is not a deadly weapon. You could kill someone with this, yes, but it would have to be such an elaborate scenario that you'd be better off using a slingshot.[/quote] I have no idea what Master of Orion is. I assume it's a game or a film. I got my facts off wikipedia. . A class 4 laser
"By definition, a class-4 laser can burn the skin, in addition to potentially devastating and permanent eye damage as a result of direct or diffuse beam viewing"
As for pilots, maybe you should fact check http://en.wikipedia.org/wiki/Lasers_and_aviation_safety Even temporary blindness for a pilot is extremely dangerous. That goes for any other vehicle. And as that says a legal 5Mw can cause a distracting glare at 400 yards.
As for the hand thing, no, no they could not block it. Again, to quote "If the laser is sufficiently powerful, permanent damage can occur within a fraction of a second, faster than the blink of an eye". A class 4 laser is such a device. "Sufficiently powerful visible to near infrared laser radiation (400-1400 nm) will penetrate the eyeball and may cause heating of the retina" You will note that the laser in question is 445nm, ergo in the category of penetrating the eyeball.
