Composite solitons and two-pulse generation in passively mode-locked lasers modeled by the complex quintic Swift-Hohenberg equation.

Multisoliton regime of pulse generation by lasers passively mode locked with a slow saturable absorber

The passively mode-locked laser1–5 has been a muchstudied device in recent years. Ultrashort-pulse generation in laser systems makes use of a variety of schemes, including figure-of-eight fiber laser design,1 fast saturable absorbers,4 additive-pulse mode locking,5 and nonlinear polarization rotation.6,7 The use of a semiconductor saturable absorber mirror8 with a relatively slow response time ...

Dissipative soliton resonances

We have found a dissipative soliton resonance which applies to nonlinear dynamical systems governed by the complex cubic-quintic Ginzburg-Landau equation. Specifically, for particular values of the equation parameters, the soliton energy increases indefinitely. These equation parameters can easily be found using approximate methods, and the results agree very well with numerical ones. The pheno...

Hybrid Mode Locked Fiber Ring Laser

Mode locked pulse generation has been reported using both active and passive mode locking schemes. Active mode locking technique has been proven to be an effective way to generate high-repetition-rate pulses by incorporating a modulator inside the laser cavity. Compared to actively mode locked lasers, passively mode locked lasers can generate pulse train at ultrashort pulse width but with relat...

Boundary tracking algorithms for determining the stability of mode-locked pulses

We develop robust computational methods, referred to as boundary tracking algorithms, that can rapidly determine the existence and stability of pulses in passively mode-locked laser systems over a broad parameter range. Applying the boundary tracking algorithms to the cubic–quintic mode-locking equation, we find a rich dynamical structure. © 2014 Optical Society of America OCIS codes: (000.3860...
