position 1 is to say "LASER RADIATION--AVOID DIRECT EXPOSURE TO BEAM"
position 3 is to say "CLASS IIIb LASER PRODUCT"
position 2 is to follow: "Each Class II, III, and IV laser product shall state in appropriate units, at position 2 on the required warning logotype, the maximum output of laser radiation, the pulse duration when appropriate, and the laser medium or emitted wavelength(s)."
And that's technically the sticker you're supposed to put on in the US to make the FDA happy
The only thing I have to add is that you use the caution logotype for lasers less than 2.5 mW/cm2 and danger for laser with more than 2.5 mW/cm2 of irridiance.
;D good idea!
apparently thare are mirrors on the moon (man-made of course!) and if you shine a powerfull laser at that part of the moon at the right time and look in a tellescope, you will see it bounce back! MUHAHAHAHA!
well on one of the nasa missions, they set up laser mirrors to guage the distance of the moon accurately, i think they are on the "sea of tranquility".
