Abstract Since the introduction of the Z-scan, which is widely used to measure the nonlinear optical properties of material. The result of measurement mainly depends on light through the sample after a slight variation in the intensity, and the tiny change depends on the accuracy of the measurement sensitivity of Z-scan technology. Measurement scheme of the optical signal for nonlinear characterization and transmission beam design can improve the sensitivity of Z-scan technique.
