光子晶体光纤产生相干反斯托克斯拉曼散射显微镜光源的数值研究
Numerical Analysis of Illuminant Generation in Photonic-crystal Fiber for Coherent Anti-Stokes Raman Scattering Microscopy
本文模拟了熔石英芯光子晶体光纤（PCF）的色散性质，并利用慢变包络近似的标量波理论计算了中心波长800.9nm的飞秒激光脉冲在两种不同色散性质的PCF中传输产生的超连续频谱，比较分析了高阶色散、自变陡和脉冲内拉曼散射对超连续谱特性的影响，考虑以上因素，设计出相干反斯托克斯散射（CARS）共焦显微成像需要的超连续光源。
In this paper, the dispersion features of photonic-crystal fibers(PCF) were numerically simulated and the effect of PCF’s parameters on its dispersion was obtained.Then the nonlinear propagation in photonic-crystal fibers of femtosecond laser pulses with center wavelength in 800.9nm was investigated theoretically. Finally supercontinuum generation in two kinds of PCF whose zero-dispersion wavelengths are different were analysed when the femtosecond laser pulses propagate in the fibers’s anomalous dispersion regime taking high-order dispersion, self-steepening and Raman scattering into account .
