(color online) The laser pulse of the probe beam. (a) The probe beam working at single-pulse model with duration of 30 ps. (b) The probe beam working at multi-pulse model. There are two main pulses, which are separated by 10 ns. The first main pulse duration is 30 ps; the second main pulse consists of 4 single pulses, whose duration is about 1.2 ns.
