报道了一种带有周期性双折射光纤滤波器的全正色散多波长被动锁模耗散孤子掺镱光纤激光器.通过数值模拟发现加入滤波器后激光器能输出多波长耗散孤子脉冲,调节滤波器带宽大小可以得到不同波长个数和波长间隔的多波长锁模耗散孤子脉冲.在激光器产生的四波长和五波长耗散孤子脉冲中观察到了耗散孤子分子,并且通过调节滤波器参数和饱和功率可以改变多波长脉冲中耗散孤子分子的个数和波长.这是在被动锁模光纤激光器中首次实现包含有耗散孤子分子的多波长脉冲.另外还在实验上实现了全正色散双波长被动锁模耗散孤子的产生.
An all-positive dispersion multi-wavelength passive mode-locked soliton-doped ytterbium-doped fiber laser with a periodic birefringent fiber filter is reported.It is found through numerical simulation that the laser can output multiwavelength dissipative soliton pulses and adjust the filtering The multi-wavelength mode-locked dissipative soliton impulses with different wavelength and wavelength can be obtained by the bandwidth of the device.The dissipative soliton molecules are observed in the four-wavelength and five-wavelength dissipative soliton pulses generated by the laser, and by adjusting the parameters of the filter and The saturation power can change the number and wavelength of dissipative soliton molecules in multi-wavelength pulse, which is the first time that a multi-wavelength pulse containing dissipative soliton molecules is realized in a passive mode-locked fiber laser. In addition, Generation of Two Wavelength Passively Mode Locked Dissipative Solitons.
