摘　　要：利用飞秒泵浦－探测技术，在７７Ｋ温度下测量了ＺｎＳｅ－ＺｎＳ多量子阱材料的光学吸收非线性时间特性，其上升时间为１０ｐｓ，恢复时间为１４ｐｓ．讨论了其产生机制为带填充．The time dependence of nonlinear optical absorption in ZnSe ZnS MQWs has been measured by using pump probe technique at femtosecond scale at 77K. It appears that the nonlinear response in ZnSe ZnS MQWs is about 10ps and the turn off time is about 14ps at 77K. The mechanism of nonlinear optical absorption is due to band filling of excitonic states.
