摘要
基于Z扫描的基本理论,根据强光光束在非线性介质中的特殊传播规律,改变光路的几何排列及光阑孔径,计算了不同情况下光阑的归一化透过率,从而确定各个参数对限幅效果的影响,得出最佳的几何排布,以实现限幅器的优化设计。
Based on z-scan theory, different normalized transmittances of the aperture are calculated when the geometry arrangement and size of the aperture change by using beam propagation in nonlinearity media. The effect of each parameter on the optical limiting is analyzed, and the optimum arrangement is designed for the optimization of optical-limiting instrument.
