What magnitude of laser power would you estimate to be required to cause retinal damage at say 1 mile for what period of time? If I may change to a different laser wavelength with a conforming lens, a 1 megawatt laser will cause nearly instantaneous, and irreversible, damage at ranges beyond one mile. So you figure that 1-megawatt is the MINIMUM power necessary? Given the fact that the majority of homes in the US are served by a 24-kilowatt (2.4% of a megawatt) electrical service, it's not likely that any retinal damage is possible without browing out half a neighborhood. :-) |
