摘要
我们以强双光子吸收BDPAS和BDBAS分子体系为介质，从严格数值求解Maxwell—Bloch方程出发，研究了飞秒脉冲激光在介质中的传播过程．研究结果表明这两种分子都具有较强的光限幅效应，且BDPAS分子的光限幅效应比BDBAS分子的更明显．分子介质的光限幅效应随着分子介质厚度的增加而增加．
Taking strong two -photon absorption （TPA） organic medium BDPAS （4, 4＇ -bis （diphenylamino） stilbene） and BDBAS （4,4＇ - his （ di - n - butylamino） stilbene） as examples, we study the propagation of femtosecond pulse lasers in the media based on the numerical solutions of the coupled Bloch and Maxwell＇s equations. The results show that these media have obvious optical power limiting behavior, and the behavior of BDPAS is better than that of BDBAS. The optical power limiting behavior becomes stronger as the thickness of the medium is increased.
