In this study, we demonstrate the optimization of the chopper frequency and duty cycle in a Z-scan measurement with a 250MHz high-repetitionrate(HRR)femtosecond laser to minimize the thermal lensing effect due to cumulative heating of the sample. The result shows that such minimization can be achie...
