Abstract

Ultrafast fiber lasers are indispensable components in the field of , and their continuous performance advancements are driving the progress of this exciting discipline. possess unique properties, such as a large fractional evanescent field, flexible and controllable , and high nonlinearity, making them highly valuable for generating ultrashort pulses. Particularly, in tasks involving mode-locking and and nonlinearity management, MNFs provide an excellent platform for investigating intriguing and related phenomena, thereby promoting the advancement of ultrafast fiber lasers. In this paper, we present an introduction to the mode evolution and characteristics of MNFs followed by a comprehensive review of recent advances in using MNFs for applications including evanescent field modulation and control, and nonlinear management techniques, and nonlinear dynamical phenomenon exploration. Finally, we discuss the potential application prospects of MNFs in the realm of .
