I was wondering how much of that 100gW is lost in Earth's atmosphere - my naive assumption would be quite a bit, but maybe not so much that it would make sense

I was wondering how much of that 100gW is lost in Earth's atmosphere - my naive assumption would be quite a bit, but maybe not so much that it would make sense to try and get the laser into orbit (also orbiting gigawatt laser would make everyone nervous, I imagine...)

They suggest using a frequency that minimises absorption by the atmosphere, and run the numbers. It's pretty interesting.
