Linear dependence of the time shift of an amplified pulseon the energy extraction from a laser amplifier

Abstract: It is shown that the time shifts of the intensity maximum and B-integral for an ampliéed laser pulse are proportional to the energy extraction from the ampliéer normalised to the saturation energy, the proportionality coefécient being equal approximately to 1/7 and 1/14 of the pulse duration, respectively. Simple analytic expressions are obtained for the maximum values of the output intensity and B-integral. The results are experimentally conérmed by ampliécation observed in a Nd : YLF crystal.

The effect of a step-wise change in the pillar density on the dynamics of droplets is investigated via three-dimensional lattice Boltzmann simulations. For the same pillar density gradient but different pillar arrangements, both motion over the gradient zone as well as complete arrest are observed. In the moving case, the droplet velocity scales approximately linearly with the texture gradient. A simple model is provided reproducing the observed linear behavior. The model also predicts a linear dependence of droplet velocity on surface tension. This prediction is clearly confirmed via our computer simulations for a wide range of surface tensions.

Drastic Suppression of Noise-Induced Errors in Underdamped Long Josephson Junctions

The fluctuational propagation of solitons (magnetic fluxons) in long Josephson junctions is studied both numerically and analytically. It is demonstrated that operation in conditions where solitons are subjected to Lorentz contraction for a significant part of the junctions length leads to drastic suppression of thermal jitter at the output junction end. Specifically, for large-to-critical damping and small values of bias current, the physically obvious dependence of the jitter versus length σ~√L is confirmed, while for small damping starting from the experimentally relevant α=0.1 and below, strong deviation from σ~√L is observed, up to nearly complete independence of the jitter versus length, which is supported by the obtained theory.
