A semianalytic approach based on the moment method is used for investigating pulse evolution in mode-locked lasers in which intracavity dispersive and nonlinear effects play a significant role. Its application to an FM mode-locked laser allows us to perform fast parametric studies while predicting the important pulse parameters. When third-order dispersive effects are negligible, a fully analytic treatment is developed that predicts how cavity parameters affect the final steady state. Our analytic approach also allows us to predict relaxationoscillation behavior as the pulse approaches its steady state. We use this technique to investigate novel aspects specific to FM mode-locked lasers such as stability of and switching between the multiple steady-state solutions. All results obtained are in excellent agreement with numerical simulations.

“…Later, Kärtner et al applied soliton perturbation theory to show that a stable soliton can exist in an AM mode-locked laser which incorporates dispersive and nonlinear elements [8]. Other relevant work numerically compared both AM and FM mode-locked lasers to show that, in the presence of a Kerr medium, both pulse profiles become increasingly "sech-like" as either the gain is increased [9] or the modulation depth is decreased (AM only) [10]. More recent efforts have addressed soliton stability in AM mode-locked, inhomogeneously broadened, lasers [11].…”

A high-repetition-rate ytterbium fiber laser, harmonically mode-locked using a phase modulator, is investigated experimentally, numerically, and analytically. Experimental results agree well with numerical simulations using the measured parameter values. By employing a few approximations, our model is cast in terms of a Ginzberg-Landau equation. This equation has known analytic solutions that agree well with the results of the full model in the appropriate limit. Pulse stability is also investigated numerically with an emphasis on the role of third-order dispersion.

“…Although general distributed models, such as the Ginzburg-Landau equation, can be used to unveil universal pulse dynamics [4], the visualization of intracavity dynamics as well as the optimization of cavity parameters imply a more precise modeling of light dynamics in fiber lasers. The latter is commonly based on parameter-managed electric-field propagation equations that follow the succession of the active and passive fibers of the cavity, in addition to the transfer functions of the lumped cavity elements, such as saturable absorber (SA), coupler, and spectral filter [7][8][9][10][11][12][13][14].…”

Strength and weaknesses of modeling the dynamics of mode-locked lasers by means of collective coordinates

We address the efficiency of theoretical tools used in the development and optimization of mode-locked fiber lasers. Our discussion is based on the practical case of modeling the dynamics of a dispersion-managed fiber laser. One conventional approach uses discrete propagation equations, followed by the analysis of the numerical results through a collective coordinate projection. We compare the latter with our dynamical collective coordinate approach (DCCA), which combines both modeling and analysis in a compact form. We show that for single pulse dynamics, the DCCA allows a much quicker solution mapping in the space of cavity parameters than the conventional approach, along with a good accuracy. We also discuss the weaknesses of the DCCA, in particular when multiple pulsing bifurcations occur.
