(north hemisphere) for an axially symmetric beam configuration. The intensity profiles have been normalized to one (
) and the scale colour ranges from 0 to 1. Full dots correspond to the north pole and the grey curve is the equator projection on the focal planes.

normalized to one (north hemisphere) for the LMJ configurations A–D. The power imbalance is given by the parameter 
and the laser intensity scale colour varies linearly from 0 to 1.
