1.55 µm AlGaInAs/InP sampled grating laser diodes for mode-locking at THz frequencies [PDF]
We report mode locking in lasers integrated with semiconductor optical amplifiers, using either conventional or phase shifted sampled grating distributed Bragg reflectors(DBRs).

Laser mode-locking with saturable absorbers [PDF]
In this paper we describe a mode-locked laser in terms of traveling pulses of light. We show that the energy absorbed by a saturable absorber is a minimum if the pulselength is a minimum, and that two pulses are essentially as favorable as one if they ...

Irrational mode locking in quasiperiodic systems [PDF]
A model for ac-driven systems, based on the Tang-Wiesenfeld-Bak-Coppersmith-Littlewood automaton for an elastic medium, exhibits mode-locked steps with frequencies that are irrational multiples of the drive frequency, when the pinning is spatially ...

Increased reliability of passive mode-locking a multi-atmosphere TE CO2 laser by injection mode-locking [PDF]
By injection of manosecond pulses from an AM mode-locked TEA CO2 laser in a passive mode-locked multi-atmosphere TE CO2 laser the shot-to-shot reproducibility of the generated subnanosecond pulses was increased to almost 100%

Active mode-locking via pump modulation in a Tm-doped fiber laser
We propose and experimentally realize a new class of actively mode-locking technique using pump modulation for rare-earth doped fiber lasers. A Tm-doped fiber laser at 2 μm is mode-locked using the proposed active mode-locking via pump modulation ...

Bound Soliton Fiber Laser Mode-Locking Without Saturable Absorption Effect
Stable bound soliton laser mode-locking is experimentally demonstrated in an environmentally stable hybrid mode-locked Er-doped fiber laser without incorporating (equivalent) nonlinear saturable absorption effects.

The wavelength tunability of all-normal-dispersion (ANDi) ytterbium (Yb)-doped mode-locked fiber laser is experimentally investigated, where the laser is mode-locked by nonlinear polarization rotation and the wavelength is adjusted by an intracavity ...

Mode-locking in ac-driven vortex lattices with random pinning
We find mode-locking steps in simulated current-voltage characteristics of ac-driven vortex lattices with {\it random} pinning. For low frequencies there is mode-locking above a finite ac force amplitude, while for large frequencies there is mode-locking

Spatio-Temporal Mode-locking in Quadratic Nonlinear Media
A new theoretical model is developed to characterize spatio-temporal mode-locking (ML) in quadratic nonlinear media. The model is based on the two-dimensional nonlinear Schr\"odinger equation with coupling to a mean term (NLSM) and constructed as an ...
