(a) (i) Heat maps of the temperature at the depth of the laser focus. The laser pulses are scanned from the bottom to the top. (ii) The peak temperatures of each beam plotted against the number of photoexcitations. The red dotted line indicates the 15th photoexcitation, where the peak temperature saturates. (b) Temperature history at the centre of the 15th photoexcited region by each beam of (i) single beam, (ii) double beams and (iii) four beams. Time zero is defined at the point corresponding to the 15th photoexcitation event. The temperature was normalized by the temperature rise by a single photoexcitation, ΔTex. (c) (i) Normalized simulated temperature rise by pre-heating plotted against the number of beams. (ii) The energy window plotted against the simulated temperature rise by pre-heating.
