摘要
研究了多光子非线性Compton散射对入射光脉冲在强双折射光纤中传输的影响,给出了光脉冲传输满足的非线性薛定谔方程,讨论了光的偏振方向沿两个双折射轴的分量强度相等时,在正常色散区和反常色散区所产生的调制不稳定性.结果表明:在不同的色散区,对应不同的功率区域,光脉冲有不同的增益谱,当双折射性质发生变化时,该增益谱比散射前有更加明显的不同.
The paper has studied the influence of the propagation in the high instability fiber of the multi-photon nonlinear compton scattering, given out Schroedinger equations met by incident optical pulse, and discussed the vector modulation instabilities both in the anomalous dispersion regime and normal dispersion regime when the intensities along the two birefringence axes are equal. The results show that the optical pulses have different gain spectra in the different dispersion and power areas. When the change of the birefringenee takes place, the gain spectra is different from that before the scattering.
