研究了放在Ｎｄ：ＹＡＧ激光腔内的含富勒烯样品对激光波形的影响。实验发现，富勒烯的强非线性吸收可用于光滑纳秒范围的自锁模脉冲序列，估计这是由于双光子吸收引起的。 The influence of the samples containing fullerenes placed in the Nd: YAG laser cavity on the laser waveforms was investigated. It has been found experimentally that the strong nonlinear absorption of fullerene can be used in the self-mode-locked pulse sequence in the smooth nanosecond range, which is estimated to be due to the two-photon absorption.
