Direct ultrashort pulse generation by intracavity nonlinear compression
L. M. Zhao, D. Y. Tang, T. H. Cheng
Direct generation of ultrashort, transform-limited pulses in a laser resonator is observed theoretically and experimentally. This constitutes a new type of ultrashort pulse generat…

Self-started unidirectional operation of a fiber ring soliton laser without an isolator
L. M. Zhao, D. Y. Tang, T. H. Cheng
We demonstrate self-started mode-locking in an Erbium-doped fiber ring laser by using the nonlinear polarization rotation mode-locking technique but without an isolator in cavity.…

Bound states of dispersion-managed solitons in a fiber laser at near zero dispersion
L. M. Zhao, D. Y. Tang, T. H. Cheng
We report on the observation of various bound states of dispersion-managed (DM) solitons in a passively mode-locked Erbium-doped fiber ring laser at near zero net cavity group velo…
