FIG. 2.

(a) measured for sample temperatures of 9 (squares), 115 (circles), and 240 K (up-triangles). The diamonds show a differential transmission measured with the same setup but with the 810 nm pulse as pump and the 750 nm pulse as probe, which is scaled to the same magnitude of the other curves. The dashed line shows the cross-correlation of the pump and the probe pulses, calculated using the known pulse widths. The inset shows the decay time of the differential transmission signal for various lattice temperatures. (b) Carrier temperature (left axis) and average carrier energy (right axis) deduced from the curve at 9 K. The inset shows the deconvolution of the probe pulse.

FIG. 3.

Normalized for pump fluences of 22 (squares), 44 (circles), 92 (up-triangles), and (down-triangles) for a fixed sample temperature of 293 K. The inset shows the peak for various pump fluences.
