摘要
在测量非线性折射率和双光子吸收系数的频率分辨双光束耦合抽运 探测技术中,光场的空间分布没有得到考虑。研究了入射飞秒光脉冲的空间分布对实验结果的影响。对不同部位的探测光进行测量可以得到完全不同的结果,用所发展的理论给出了解释。通过数值拟合获得了磷化镓(GaP)在飞秒激光脉冲作用下的非线性折射率和双光子吸收系数。进一步可能从实验上主动选择适当的空间滤波来获得频率 空间分辨信号。
Abstract
The effects of spatial distribution on the experimental results are studied in spectrally resolved two-beam coupling pump-probe technique. Results may be totally different when different spatial region of probe field is chosen to be measured. Interpretation is given using the theory presented in this paper. Nonlinear refractivity and two-photon absorption of GaP are obtained by numerical fitting the experimental results. Spatial-spectral resolved signal may be obtained by using appropriate spatial gates.
