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 ...

IEEE Journal of Selected Topics in Quantum Electronics, 2000
The evolution of the theory of mode-locking over the last three and a half decades is reviewed and some of the salient experiments are discussed in the context of the theory. The paper ends with two-cycle pulses of a mode-locked Ti:sapphire laser.

A theory of noise in mode-locked lasers is developed that applies to additive pulse mode-locked and Kerr lens mode-locked systems. Equations of motion are derived for pulse energy, carrier linewidth, frequency pulling, and timing jitter. The effect of gain fluctuations, mirror vibrations, and index fluctuations are determined.

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 ...

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
