Figure 2
(a) Dependence of the oscillatory component using a spectrally controlled pump pulse on the pump power depicted by the open circles. The solid curves indicate the fitting results. (b) The evaluated amplitude and dephasing rate are plotted as a function of the pump power by the closed and open circles, respectively. The dashed line indicates the dephasing rate of an uncontrolled pump pulse at 1 μJ/cm2.
