Transport of a colloidal particle driven across a temporally oscillating optical potential energy landscape [PDF]

open access: yesNew Journal of Physics, 2019
A colloidal particle is driven across a temporally oscillating one-dimensional optical potential energy landscape and its particle motion is analysed. Different modes of dynamic mode locking are observed and are confirmed with the use of phase portraits.

Laser mode-locking with saturable absorbers [PDF]

open access: green, 1967
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 ...

OBSERVATION OF MODE LOCKING AND ULTRASHORT OPTICAL PULSES INDUCED BY ANTISOTROPIC MOLECULAR LIQUIDS [PDF]

open access: bronze, 1968
Mode locking and ultrashort pulses have been produced in a giant-pulse ruby laser with heated nitrobenzene (T > 110°C) or -chloronaphthalene (T > 62°C) inside the optical resonator.

Mode Locking in ac-Driven Vortex Lattices with Random Pinning [PDF]

open access: green, 2001
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

Dynamics Simulation of Self-Mode-Locking in a Semiconductor Disk Laser Using Delay Differential Equations

open access: yesPhotonics, 2022
Self-mode-locked semiconductor disk lasers possess compact resonant cavity and stable construction. These devices have a wide application prospect because of their picosecond to sub-picosecond pulse width, excellent beam quality and tailorable emission ...

Relocking and Locking Range Extension of Partially Locked AMLL Cavity Modes with Two Detuned RF Sinusoids

open access: yesPhotonics, 2023
Actively mode-locked fiber ring lasers (AMLLs) with loss modulators are used to generate approximately 100ps pulses with 100MHz repetition. RF detuning around the fundamental frequency, f0, causes a loss in phase lock (unlocking) of cavity modes and ...

Mode-locking of lasers

open access: yesPhotoniques, 2023
Mode-locked lasers are the fundamental source of ultrashort and ultraintense light pulses and a principal pathway for three Nobel Prize technologies: optical frequency combs, chirped pulse amplification, and attosecond light pulses. They are essential in routine and high-level applications such as refractive surgery, spectroscopy, or metrology.

Revealing the Evolution from Q-Switching to Mode-Locking in an Erbium-Doped Fiber Laser Using Tungsten Trioxide Saturable Absorber

open access: yesPhotonics, 2022
Passively Q-switching and mode-locking technologies can generate short pulses with durations that differ by several orders of magnitude widely used in different applications.

Mechanisms of spatiotemporal mode-locking [PDF]

open access: yesNature Physics, 2020
Mode-locking is a process in which different modes of an optical resonator establish, through nonlinear interactions, stable synchronization. This self-organization underlies light sources that enable many modern scientific applications, such as ultrafast and high-field optics and frequency combs.

1/1.5 μm Synchronized Dual-Band Mode-Locked Fiber Laser

open access: yesIEEE Photonics Journal, 2021
A 1/1.5 μm dual-band mode-locked fiber laser is experimentally demonstrated. The laser is based upon an architecture in which the 1 μm and the 1.5 μm signals are generated in independent cavities that share the identical ...
