    Here's a challenge for ya. See how long you can stare directly into the laser without blinking. Just work on this for a while and report back to us.

    Mount it to your handlebars so you can have a laser guided bike.

    It's true that they can screw up your eyes if the beam is in your eye for a significant amount of time (which, admittedly is probably less than a second).

    High-output entertainment industry lasers can be 550mw+, but the beam will only harm your eye if the mechanism breaks and the beam stays in the same place (i.e., your eye). Otherwise it's actually scanning at many, many frames/second, so even if it dazzles your eye, it's only there for a short time.

    Class IIIb is pretty high risk of instantaneous eye damage if viewed directly. Only the more powerful ones will have a risk of blinding if diffused light is viewed.

    Class IIIa will blind if the beam is viewed directly.

    550mw lasers are class IV, and can potentially burn skin if left in contact long enough, and will cause eye damage. Actually I have no idea how anyone can legally use those for "entertainment", since those are considered fire hazards, and are unsafe to view the beam for any amount of time, under any condition, direct or diffused. A cutting laser is a class IV.

    I've been through quite a bit of optics training, since I have to deal with this stuff on a regular basis.

    Here's some more info on it, straight from OSHA. http://www.osha-slc.gov/dts/osta/otm...otm_iii_6.html

    OK, now I see where these lightshow lasers are getting this number....it's misleading.

    They are adding up the wattages of the multiple elements. So 10 approx 50mw lasers would be 500mw.

    I was thinking it was a single beam rating.

    Ohhh, yeah.

    The ones I have been used in stuff I've worked on were one "beam" that was split by a special prism into different wavelengths. The controller warps and changes the shape of the prism to get different colors, and then the scanner mirrors make images / beams.

    Also, now I'm remembering that in the US they were not permitted to scan over the audience, only overseas. But the risk is still very low.

    Things just haven't been the same since they made us stop spraying the mirror ball with lasers.

    I remember being invited to watch some laser experiments a p-chem friend of mine was doing in grad. school. He had all sorts of mirrors and prisms and stuff on a floating table with a huge laser contraption at one end and some materials in cuvettes in liquid nitrogen. He had me put on some goggles, then he hit the switch, I heard a click, and that was that. I asked where the beam was and he said it's on the table but it's not a visible laser. Major letdown.

    Feeble stuff. If you are not worried about safety regulations you can do better. An electronics flea market in southern California had the working head of a 40 Watt output IR CO2 cutting laser for sale for just over $100.00. In a magazine called NUTS AND VOLTS I found were I could get the 2 KW power supply needed to feed it. All for only a few thousand dollars. And the power supply cound fit in a Burley trailer with the leads running to the yard long cutting head mounted on a front rack. Anyone for burning through the tires of someone who cuts you off? Of course I found these things before 9/11. I hope Homeland Security is tracking such stuff now.

    Hmmmm, I think that could be something PhantomCow2 might be interested in.
