摘要
采用速率方程理论研究C_(60)分子实现反饱和吸收的动力学过程,以YAG倍频调Q脉冲激光照射C_(60)甲苯溶液,实验验证了理论模拟的正确性。还分析了分子各能级对反饱和吸收的贡献以及不同激光波长和脉宽对反饱和吸收的影响。
Dynamics of reverse saturable absorption (RSA) and optical limiting (OL) in C_(60) medium are studied in detail employing rate equation theory. Experimental results of RSA and OL in C_(60)toluene solution with a Q-switched frequency-double YAG laser agree well with the theoretical simulations. The contribution of each energy level of C_(60) molecule to RSA and the influence of different laser wavelength and pulse duration on RSA and OL are also dicussed.
