Critical behavior of a passively mode-locked laser: rational harmonic mode locking
Optics Letters, 2007The critical behavior of passive mode locking has been demonstrated in a figure-eight fiber laser that performs rational harmonic mode locking (RHML). On both the repetition rate and the pulse amplitude distribution, the observed pulse trains near the threshold exhibit the same regulations as the rational harmonic mode-locked ones.

Mode-locking in nonlinear rotordynamics
Journal of Nonlinear Science, 1995The paper presents a computer-assisted study of the dynamics of two nonlinearly coupled driven oscillators with rotational symmetry which arise in rotor dynamics (nonlinear Jeffcott rotor). In the variable \(x \in \mathbb{C}\) the system can be written as \[ \ddot x + \gamma \dot x + \alpha (x) \left( 1 - {\delta \over |x |} \right) x = \varepsilon ...

Journal of Applied Physics, 1968
A mode-locked Nd:YAG laser is described which produces pulses 30 psec in duration at a 2.6 nsec repetition rate. The locking range extends over ≈35 GHz, although the free-running oscillating linewidth is only about 10 GHz. Also discussed is the behavior of the phase of the pulsetrain with changing cavity length.

The technical requirements for active mode locking, as described in the previous two chapters, are not simply fulfilled. The external source for driving the modulator must be accurately frequency stabilized at the pulse repetition frequency. An alternative for obtaining short pulses, called passive mode locking, does not require these complications ...

Passively mode-locking induced by gold nanorods in erbium-doped fiber lasers
, 2013We demonstrated a passively mode-locked erbium-doped fiber laser by using gold nanorods as a saturable absorber. The gold nanorods (GNRs) were mixed with sodium carboxymethylcellulose (NaCMC) to form GNRs-NaCMC films.

Dispersion-managed mode locking
Journal of the Optical Society of America B, 1999The pulse shape and spectrum of ultrashort-pulse Ti:sapphire mode-locked lasers are explained by a model akin to dispersion-managed pulse propagation of optical communications. The pulse is characterized as a nonlinear Bloch wave in a periodic structure. The ultimate spectral width is limited by dispersion and mirror bandwidth and less strongly by gain

Turbulence in Mode-Locked Lasers
Physical Review Letters, 1999We show that the well-known instability in actively mode-locked lasers with detuning between the resonator round-trip time and the modulator period exhibits a transition to turbulence analogous to fluid flow. We derive a universal normalized detuning of the laser that plays the same role as Reynolds number in fluid flow. This is the first time that the

Passive harmonic-mode locking of erbium-doped fiber laser with atomic multilayer graphene is presented. The laser could operate at several harmonics (from 2nd to 21st) of the fundamental repetition frequency of the ring resonator (106 MHz).
