If current muli-kilowatt lasers are awesome, imagine what multi-GIGAWATT lasers will be able to do.

The medium is a mixture of U-235 hexafluoride, xenon difluoride, and helium in a container lined in calcium fluoride and copper fluoride. When the geometry is right, a fission chain reaction is enabled. Each fission ionizes helium which transfers its activation energy to xenon difluoride, an efficient lasing medium. This is a gutless wonder: no conversion into heat-electricity, but DIRECT CONVERSION of nuclear energy into light. Of course, waste heat disposal will be a major challenge.

Multi-gigawatt beams are possible in principle. Such a system in orbit around the Earth would be able to engage any enemy structure whatsoever. The beam could cut through kilometers of rock or other armor like the armor did not exist. Unfortunately, it will come too late to destroy the Iranian fascist regime, but similar regimes will doubtlessly follow, so it will be good for the USA to be ready.
