摘要

采用掺镱光子晶体光纤飞秒激光放大器为抽运源,搭建了偏振分辨的Z-scan实验系统.实验研究了块状本征磷化镓(GaP)晶体的非线性吸收和非线性折射率系数.研究证明,在中心波长1 μm飞秒激光的作用下,本征GaP晶体的非线性吸收主要为三光子吸收.而且还表明本征GaP的非线性吸收和非线性折射率系数具有很强的各项异性、偏振相关性及饱和特性.

A modified Z-scan experimental setup based on a Yb-doped photonic crystal fiber amplifier was used to achieve polarization-resolved measurement of the nonlinear properties of bulk intrinsic GaP. The experiment results reveal that three-photon absorption dominated the nonlinear absorption processe at room temperature. The anisotropy and crystal orientation dependence of the nonlinear absorption and nonlinear refractive index was experimentally studied and the nonlinearities showed saturation at high pump intensities.
