Re: 60W: Cutting a match and lighting electrical t
More like 2.5 seconds later. And you've totally ruled out divergence.
Not only that, but this wavelength is absorbed by the carbon dioxide in the air and has a divergence of 5mRad. It's not going too far. After 100 feet, it's a warm patch the size of a small pizza.
Since any laser beam is going to be a few miles in diameter at moon distance, it can't be too difficult to hit it.
