摘要：

We show that the closed aperture refractive Z-scan signatures using high-repetition rate ultrafast laser systems are strongly influenced by thermal lensing. We demonstrate that a stationary thermal lens develops even in the case of very low linear absorption. In addition, we have developed a stationary thermal lens model using the Gaussian decomposition method and applied it for the first time to Z-scan experiments and find good agreement between theory and experiment.
