FIG. 1.

(a) Experimental configuration for the all-optical pump and probe measurement technique. The red line is for the pump and the blue line is for the probe beam. (b) The (red circle) and (blue triangle) signals are shown at 297 K with a pump-beam intensity of . (c) Reflectivity (red rectangle) and Kerr signal (green diamond) differences between 297 and 310 K at a pump-beam intensity of .

Evolution of the calculated electron (dashed orange), lattice (dotted magenta), and spin (solid blue) temperature together with the energy density change of the nonthermal electron system (dot-dashed green) adopting the extended three-temperature model.
