Harmonic mode-locked fiber laser based on microfiber-assisted nonlinear multimode interference
文献摘要：
A novel harmonic mode-locked fiber laser based on nonlinear multimode interference[NL-MMI]in a microfiber-assisted ultrafast optical switch is proposed in this Letter.The microfiber-assisted ultrafast optical switch can be obtained by taper-ing the splicing point of the graded-index multimode fiber[GIMF]and single-mode fiber,which not only helps to shorten the self-imaging period in GIMF to relax the strict requirement of NL-MMI on the length of multimode fiber,but also improves the harmonic order.In the experiment,with the waist diameter of ～15 μm,the repetition rates of the fiber laser can be stably locked at 285 MHz,corresponding to the 16th-order harmonic mode-locking,with the pulse duration of 1.52 ps.Our results provide novel insight into the design of a high-repetition-rate laser and the application of microfibers in the mode-locking device.
