The outermost plasma boundary is round and is not affected by the fractal, this is because the laser is still completely symmetrical when it is just incident, and the boundary shape has also changed in the second column
The outermost plasma boundary is round and is not affected by fractals because it is still fully symmetrical when the laser first comes in, and the shape of the boundary changes in the second column
The boundary of the most peripheral plasma is circular, which is not affected by fractal. This is because it is completely symmetrical when the laser is just incident, and the shape of the boundary changes in the second column
