Build up of Nmax as a function of time (ms). 1000 Hz laser operation and 200 mJ per pulse. From bottom to top, τ = 1 ms, 2 ms and 5 ms. The total number of molecules in the crystal is 1014. The excitation efficiency r is taken as 1/40. The saturation concentrations correspond to ∼4, 6 and 12% of the total photoactive species in the crystal [equation (5)]. |
