the laser posted is SG-III for fusion research, not for weapon..lol
the current energy output for SG-III is 200 KJ, 400 KJ future upgrade..
the US and france has megajoule laser for many years now, china is way behind.
the SG-IV 1.5 MJ facility will close the gape a bit, but won't be ready until 2020.
