Role of dispersion in pulse emission from a sliding-frequency fiber laser

Abstract

We present an experimental and theoretical investigation of the role of group-velocity dispersion in the generation of picosecond pulses from a sliding-frequency fiber loop laser.

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

“…An analytical equilibrium pulse solution of this equation has been be found to exist in certain parameter regimes [5,12,14,28] that may be written…”

“…where σ > 0 is the coefficient of the quintic term [4,5,13,14], which relaxes the stability constaints posed on the term δ and enables us to find more stable pulse solutions in a broader range of the parameter space. We refer to the mode-locking equation that is formulated in Eqs.…”

Stabilized pulse spacing in soliton lasers due to gain depletion and recovery

“…In (1), the effects of intrinsic losses, bandwidth limited gain, and intensity-dependent losses have been neglected [8]- [10]. In practice, these terms are generally necessary to describe the mode-locking dynamics which result in the formation of the fundamental solitons observed experimentally [5], [6].…”

Power-Scalable, Sub-Nanosecond Mode-Locked Erbium-Doped Fiber Laser Based on a Frequency-Shifted-Feedback Ring Cavity Incorporating a Narrow Bandpass Filter

“…As a result, one can obtain a variety of unique and distinctive lasing properties from these types of lasers. Therefore, FSFLs have been investigated as coherent light sources for various applications, such as broadband continuous-wave (CW) lasers [1,2], multiwavelength lasers [3][4][5], and pulsed lasers [6][7][8][9][10][11][12]. In general, the FSF mechanism is obtained by an acousto-optic modulator (AOM), either an upshifting or downshifting type, inserted in the laser cavity.…”

“…In particular, stable mode-locked pulses can also be generated from FSFLs, and pulse durations obtained with them are typically in the order of tens of picoseconds [6][7][8][9]. To date, most experimental investigations of FSFLs have focused on achieving shorter pulses through modifying cavity configurations [10][11][12], or by combining the FSF mechanism with other mode-locking techniques, e.g., nonlinear polarization rotation [10,12].…”
