| Abstract: | The nonoptical properties of Rhodamine B solution in methanol are measured by femtoseeond pulse laser with single - beam Z - scan method. The influence of the intensity of light on the result of experiment is researched. In order to eliminate the error in the nonlinear absorption of sample＇ s pool and solvent, the sample＇ s pool and solvent are also tested by Z - scan method in the experiment. The two - photon absorption coefficient, which is processed according to the theory of thin sample is consistent with the results of other measured methods. So the validity of this measuring and processing method for organic solution material is proved. |
