A novel passively gigahertz harmonic mode‐locked all‐fiber laser based on hybrid fiber structure (single‐mode fiber–graded‐index multimode fiber–single‐mode fiber (SMS)) is proposed SMS, which coils on the paddles of polarization controller (PC), is demonstrated to modulate the temporal intensity for mode‐locking. The nonlinear absorption properties of the optical switch are controllable by adjusting the paddles of PC; such an ultrafast optical switch enables the wavelength switchable harmonic mode‐locking operation. Ultrafast pulses with 1.9 ps at 1558.41 nm and 0.95 ps at 1563.08 nm are generated. The maximum repetition rate of the laser up to 1.127 GHz harmonic of fundamental repetition mode‐locking at 1563.08 nm, corresponding to 880 order, and the output power is 4.2 mW. Considering its superiority in terms of low cost, easy integration, and high reliability, the findings validate that SMS can be used in harmonic mode‐locking.

提出了一种新型的基于混合光纤结构（单模光纤-渐变折射率多模光纤-单模光纤（SMS））的无源千兆赫兹谐波锁模全光纤激光器，该线圈盘绕在偏振控制器的桨片上（ PC）被证明可以调节锁模的时间强度。光开关的非线性吸收特性可通过调节PC的拨片来控制。这种超快速光开关可实现波长可切换的谐波锁模操作。生成在1558.41 nm处具有1.9 ps在1563.08 nm处具有0.95 ps的超快脉冲。激光的最大重复频率高达基本重复锁模的1.127 GHz谐波-锁定在1563.08 nm，相当于880阶，输出功率为4.2 mW。考虑到其在低成本，易于集成方面的优势，
