Optics Letters, 1992
Self-focusing in conjunction with an intracavity aperture creates a power-dependent amplitude modulation in laser oscillators, which allows passive mode locking. A simple analytical formalism yields closed-form expressions for the depth of passive amplitude modulation introduced by either the spatial gain profile or a hard aperture inserted in the ...

Conference on Lasers and Electro-Optics, 2020
A new mode-locking mechanism is discussed that solely relies on four-wave mixing and does not require a saturable absorber. This mechanism explains a number of previously reported peculiar findings of self-modelocking and comb formation.

Asynchronous soliton mode locking
Optics Letters, 1994We report a harmonically mode-locked erbium-doped fiber ring laser with short solitons. A phase modulator running asynchronously with the pulses provides pulse start-up, continuous background cleanup, and a new form of pulse timing stabilization. Steady-state operation of picosecond solitons at a repetition rate of 1 GHz was obtained with no need for ...

During the last decade, self mode-locking and resulting comb formation have emerged from a controversially discussed anomaly to a hot topic in semiconductor laser physics. Initial experimental reports claimed mode-locking in a cavity lacking the stabilizing action of a saturable absorber [1] .

Physical Review B, 1989
Possible modulated structures of icosahedral quasicrystals are investigated. The modulated phases are regarded as lower symmetric phases where the global icosahedral symmetry of quasicrystals is broken due to mode locking of phason degrees of freedom. With the help of group theory, nonvanishing phason fields are calculated for all the possible symmetry

Conference on Lasers and Electro-Optics, 2018
We describe, through multiple theoretical and experimental realizations, spatiotemporal mode-locking (STML), the most general form of self-organization in optical oscillators. We discuss qualitatively new kinds of mode-locking, and routes to ultrahigh power, compact lasers.
