You're still a moron. It's called "conservation of energy". You seem to have a hard time understanding the difference between power and energy.
A jelly donut and a pipe bomb may have equivalent energy content, but one has a much higher peak power.
Nevertheless, retina damage can be acheived at great distances with either pulsed or cw laser light.
Pulsed would certainly be easier and cheaper.
Hell, Reagan should have hired you for SDI then all his problems would have been solved, being the "hobbyist expert" you are and all.
I've worked on anti-missle laser systems just like hundreds of other laser jocks.
As for energy and power, I hope my physics degree meant something. Yes, I certainly do know the difference. It's you that seems to be confused. You seem to think you can get something for nothing, that lasers are 100% efficient and that they never lose energy. That's nonsense. In fact, it's precisely the difference in energy and power that makes my point. No 'hobbyist' is ever going to be able to easily generate the TOTAL amount of energy needed to penetrate miles of atmosphere. The Joules needed would be enormous.

Well, then why was SDI so difficult? According to your arguments it should have been a walk in the park. How much energy would it take to burn metal? Surely we've got lasers that can do that, don't we? The problem is atmospheric and diffraction inefficiency. If you're such a genius how is it that you don't know about those things?
