C_（60）对ps光脉冲的限幅效应

Performance of Optical Limiting in C_(60)with ps Pulse

研究了Ｃ６０甲苯溶液对ｐｓ光脉冲的限幅效应，证明了光限幅效应是单重态激发态吸收的结果；同三重态激发态吸收光限幅效应相比，单重态激发态吸收光限幅具有限幅能量低、响应速度快等优点。实验结果与理论拟合结果基本符合。

In this paper,optical limiting in C60-toluene solution for ps pulse is studied andproved to be induced from singlet excited-state-absorption.Compared with optical limiting based on triplet excited-state-absorption,this kind of optical limiting has the advantages of lower clamped energy and quicker response.The experimental results coincide with the theoretical calculations.
