      Look. Many things can be made into weapons. In the case of lasers, it is never good to be looking into a laser beam of any wattage especially as the damage to your retina (likely the retinal pigment epithelium initially) may go undetected for years, but could establish a starting off point for macular degeneration. But like the parent said, pump it up 20X in power and you are starting to be able to cause some real damage immediately.

      Well, retinal degenerative diseases and remodeling is my forte, but I do recall that red lasers in the 3-5Mw range should cause no retinal damage per se. I qualify that because the long term studies have not been done, only short term studies to my knowledge. The thing you have to remember is that lasers are coherent light that "packs" much more energy into their beam than does say a 200 watt halogen lamp which throws its energy all over the place wasting about 90% of its energy as light. So, as I recall the threshold for damage is 10Xs the acceptable wattage for lasers assuming that people will guard by blinking when exposed to a bright light. (blink time being somewhere about 2/10ths of a second). So, the currently accepted wattage figures on the threshold of immediate tissue damage are in the 30-50Mw range. But you have to remember that the criteria are somewhat vague and no long term studies (to my knowledge) have been done as to the effects on the retina and RPE of brief exposures to low wattage laser light. I might suspect that you could increase your chances for having dry macular degeneration, but that is hazarding a guess.....Regardless, a good rule of thumb is to never stare into a bright light source. (oh, and always invest in good quality sunglasses).

      ...on account of it being hard to examine the retina when there's nothing left of the head but some vapor.

      There are, however, red lasers in the milliWatt range for which the blink/aversion response is (probably) fast enough to prevent damage.

      Isn't there some minimal power below which you can blink faster than the laser can deposit enough energy to damage the retina?

      This is exactly how lasers are classified.

      You are refering to a Class II laser. It has the potential to cause damage to your eyes, but it is low enough power (and in the visible light range) so your blinking reflex will protect your eyes. Though, like looking into the sun, people can fight that reflex (usually children) and blind themselves.

      Class III lasers are the most dangerous ones, resulting in instant damage. I believe most if not all laser pointers are class 3 devices.

      Class I lasers are so low powered that you can look directly into them for a long period of time, and not cause any damage at all, as a result.

      Class III means the laser is an eye hazard. Class IIIa are hazardous if focused, class IIIb are focused as-is. There are also class IV lasers, which are burn hazards (I've worked with both) and are more dangerous than class III lasers. Most laser pointers are class IIIb, although I've seen lower. Note too that laser classification is based on power at the output, not at the source.

      "Instant damage" is a bit over-stated, but class IIIb lasers (especially at the >100mW levels in the original article) are most definitely capable of causing retinal damage.

      A pet toy and exerciser which produces an automatically movable, outwardly projected laser beam. The function thereof is to provide virtual "prey" for the stimulation and exercise of an animal. The device, which does not include a conventional motor, is small (e.g., can be handheld), lightweight, battery operated and silent, and has an extremely long potential cycle life. Electrically energized nitinol wires deflect a visible laser module to produce a virtual laser light target moved through three dimensions.

    Security codes were assigned based on the UV spectrum, with Infrared being the lowest, and Ultraviolet the highest. The clothing and similar worn by people had to match their colour (or Black for IR and White for UV).

    Lasers were the standard weapon in the game, and were coded according to the clearance of the firer. Reflective armor, protecting against lasers, was also coded by colour and couldn't protect against any laser of a shorter wavelength - so people had no protection of those of higher clearence than themselves.

The Computer has imposed an unbreakable system of security clearances that represent how much it trusts a given citizen. The security clearances are keyed to the colors of the spectrum. The lowest security clearance is INFRARED, meaning The Computer doesn't trust you at all; INFRARED citizens wear black. RED Clearances is the next highest, followed by ORANGE, YELLOW, and so on up to VIOLET. Above VIOLET Clerance are the illustrious High Programmers, the ULTRAVIOLETs, who can program The Computer itself. High Programmers wear white.

    The classifications are based upon wattage levels which will cause damage to the eye before your brain reacts AND the eyelid closes.

    Anything over a certain class (II or III, I forget which) falls into the 'damage will happen before you blink" category. That's why they usually require a keylock on a shutter or output control, a lasing indicator light, etc. OSHA regs then mesh in with this- lasers in operation over a certain level mean guards on equipment, goggles for anyone in the room, blah blah.

    Over a certain level in mW also requires approval from the FAA to use outdoors [at night] as it could blind pilots. Sounds silly for a single point source, but it's intended for laser light shows where hundreds or thousands of beams- which often sweep/scan out into the sky- stand an excellent chance of blinding a pilot.

Just mount a spinning mirror to the bottom of a regular power mower and shine the laser down on it. You could even diffuse the beam so that it becomes "non-lethal" after 1 meter or so. It wouldn't even have to have an grass discharge outlet (clippings (c|w)ould burn up completely?) that usually let's all kinds of objects fly out at you.

Think about it; how many times have you run across rovers dog bone remains and had them shoot out at high speed? What about accidentally sticking your foot/hand in the path of the blade?

That's about 11 feet. Now, I suppose that if you could get within 11 feet of the pilot you might be able to blind him if he didn't see you standing there with a laser but from that distance you could just throw a rock into the turbine and blow the engine up.

    More likely, if you are in the pilot blinding business you are going to be a good few thousand feet away. Add in to that that it's going to be difficult to find a place where you can stand and get line of sight into the pilots eyes. I don't know about you, but when I look up at a plane I see the bottom, which is usually made of metal, not glass. I'll give that if you tried real hard you might be able to find a tall hill within a few thousand feet of the airport that would give you line of sight to the pilots eyes.

    Now that you've got your hill, and your laser and a plane is taking off (or landing) facing directly at you you just need to aim it right at his eyes. I'm assuming here that you have mounted some huge scope to the laser so you can *find* the pilot's eyes from 1000+ feet. And probably a tripod. All that's left is to hold that beam right on his eye for several seconds while he's moving, the plane's moving and you are moving. Don't forget the beam is going to be spread out some at that distance, which means less power per square centimeter which means you have to hit him longer.
