| 摘 要： | 提出了一种通过测量单脉冲光的输入与输出波形来研究激发态非线性吸收的新方法，用这种方法研究了纳秒脉作用下类卟啉镉溶液与甲基橙溶液的三重激发态的非线性吸收特性，前者为反饱和吸收现象，后者是由饱和吸收转化为反饱和吸收的新现象，实验结果验证了理论模拟和正确性。

| Abstract: | A new method for studying excited state nonlinear absorption through measuring the temporal profile of input and output single laser pulses was presented. Using this method, the transient excited state nonlinear absorption of the solution of cadmium texaphyrin like in chloroform ((TXP)Cd) and the solution of methyl orange are demonstrated by the ns laser pulse. The reverse saturable absorption in (TXP)Cd and the combination of saturable absorption and reverse saturable absorption in methyl orange are observed, respectively. The theoretical simulations agree well with the experiment results. |
