Fraction of MPET reached by a combination of PRR and J0, for T = 0.01, 0.1,1 and 10 s, and t = 1 ns. The black solid line represents the locus where J0 equals the MPEs. The dashed grey lines represent the loci where the power is constant, and the labels are expressed in mW. These plots refer to the UVA region (315-400 nm), for 1 ns < (T,t) < 10 s
