利用掺铒光纤环形激光器(EDFRL),基于光纤的非线性克尔效应,实验实现了多波长混沌激光输出。实验研究了EDFRL在时序上通过倍周期进入混沌的路径,并进行了理论分析,理论研究与实验结果一致。实验结果表明,随着抽运功率的增加,其光谱的输出呈现多波长,激光器最多可输出5个不同波长的混沌激光。采用光纤光栅进行滤波后,各个波长的输出均呈现混沌状态。 Using erbium-doped fiber ring laser (EDFRL), multi-wavelength chaotic laser output is experimentally realized based on the nonlinear Kerr effect of optical fiber. The path of EDFRL into chaos through time period is experimentally studied, and the theoretical analysis is made. The theoretical research is consistent with the experimental results. The experimental results show that with the increase of pumping power, the output of the spectrum shows multiple wavelengths, and the laser can output up to five chaotic lasers with different wavelengths. After filtering with fiber grating, the output of each wavelength presents a chaotic state.
