When we say "normalized", it means to normalize the fields with respect to the source signal, eg, to remove the frequency-dependency of the injection signal. Please refer this post Ansys Insight: 关于光源的归化问题:频谱和功率

If you want to normalize the intenisty with maximum such as at the focus plane, you can just use I(x,y)/max(I(x,y)).
