摘要：

Using 9 fs UV laser pulses, laser induced ultrafast dynamics in fused silica is investigated in the present study. The free carrier dynamics under few-cycle UV laser excitation far below laser damage threshold in the fused silica was studied. After laser excitation, free carrier in the conductive band is found to turn into self-trapped excitons within about 300fs. It is possible that the trapped exciton will result in the incubation effect under the condition of ultrafast high-frequency pulsed UV laser exposure.
