We numerically and experimentally demonstrate the generation of broad bandwidth mode-locked dual-wavelength pulses with diverse-pattern from a dispersion managed erbium-doped (Er-doped) fiber laser. The two-peak gain profile of the Er-doped fiber is shown to have advantages in achieving broadband dual-wavelength pulses compared to a comb filter in our cavity. Our obtained bandwidths of 24 nm and 11.5 nm represent the broadest achieved in an Er-doped dual-wavelength fiber laser to date. In addition, the weak third-order dispersion (TOD) of the fibers facilitates two dispersion-pattern pulses (one stretched pulse and one dissipative soliton) generated in the near zero dispersion regime. Our results provide a convenient, effective way to obtain such sources for potential applications, such as in dual-comb metrology and multicolor pulses in nonlinear microscopy.

宽带双波长光纤激光器同时提供拉伸脉冲和耗散孤子

我们通过数值和实验证明了从色散管理的掺((掺r)光纤激光器产生具有不同图案的宽带锁模双波长脉冲。与我们腔中的梳状滤波器相比,掺Er光纤的两峰增益曲线显示出在实现宽带双波长脉冲方面具有优势。我们获得的24 nm和11.5 nm带宽代表了迄今为止掺Er双波长光纤激光器中获得的最宽带宽。此外,光纤的弱三阶色散(TOD)有助于在接近零色散状态下生成两个色散模式脉冲(一个拉伸脉冲和一个耗散孤子)。我们的结果提供了一种便捷有效的方法来获取潜在应用的此类资源,
