Laser mode-locking with saturable absorbers [PDF]

, 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 ...

Dually-mode-locked ND: YAG laser [PDF]

, 1974
Mode-locking is stabilized effectively by conventional loss-modulator and phase-modulator, mode-locking elements placed in laser cavity in optical series with one another.

Mode-locking in ac-driven vortex lattices with random pinning

, 2000
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

Irrational mode locking in quasiperiodic systems [PDF]

, 2007
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 ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Mode-Locked Operation of High-Order Transverse Modes in a Vertical-External-Cavity Surface-Emitting Laser

Sensors
Understanding the mechanism of mode-locking in a laser with high-order transverse mode is important for achieving an ultrashort pulses train under more complicated conditions.

Observation of mode locking and ultrashort optical pulses induced by antisotropic molecular liquids [PDF]

, 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.
