I remember when the phrase "if nothing else, just to see a 5 Megawatt laser fire" inspired boy genius Chris Knight to finish college.
Now, we have a laser which "lasting just a few nanoseconds, the system is capable of generation 500 trillion watts of power"
All I can say to that is: look what you have high power, limited firing time, unlimited range. All you need is a large spinning mirror and you could vaporize a human target from space...
I hope a responsible agency knows about this.
