If your 300TW Hercules Laser can maintain (CW) it's beam power for a second, how many seconds will destroy abovementioned meteorite? If you need to aim this Laser at a meteorite that's still thousands of kilometeres in space, what will the Laser's divergence be in mRad? You obviously need a extremely low divergence to focus / aim a Laser over such a distance. I would love to get a answer on this. South Africa's got the perfect site for such a Laser at Sutherland. (Some of the worlds largest Deep Space Telescopes can be found here) If you want to build a powerful LASER for space defense, e.g. to destroy Meteorites, what power Laser will destroy say a 10KM Dia. meteorite?
