No, the ignition here is small - on the order of a stick of dynamite. There's no reasonable way to scale it up to the size of a hydrogen bomb. Even if the laser

No, the ignition here is small - on the order of a stick of dynamite. There's no reasonable way to scale it up to the size of a hydrogen bomb. Even if the lasers could just be scaled up larger & still work, which they can't b/c the lasers would make too dense of plasma & block their own beams, the number you'd need & the geometry of trying to use it on a full scale bomb would be totally impractical even for a single test. Also, a city sized laser ignition source w/ a bomb at the middle wouldn't be a useful weapon even if it were possible
