Isochronic control of the carrier-envelope phase-shift

Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009
Experiments in extreme nonlinear optics, in attosecond physics, and in frequency metrology depend on precise control of the carrier-envelope phase (CEP) of femtosecond oscillators and amplifier systems. Today intracavity fine CEP control relies mostly on pump-laser amplitude modulation [1], which is intrinsically fast but has only a limited control ...

Stable adaptive controller design for uncertain phase shift

IFAC Proceedings Volumes, 2004
Abstract In order to construct stable adaptive control systems, several assumptions are needed, and those require some prior information of unknown plants, such as degrees and relative degrees. However, those assumptions sometimes become too restrictive, since it is difficult to obtain reasonable estimations of those indices a priori for unknown ...

Phase-shift control of the exchange coupling between magnetic impurities

Nanotechnology, 2020
Abstract The control of magnetic interactions is one of the most relevant topics in spintronics. In this work, we propose to use electric potential barriers for tuning or even suppressing the RKKY exchange coupling between magnetic impurities in a two-dimensional electron gas.

Analysis of Phase-Shift Controlled Thermoregulator Circuits

Review of Scientific Instruments, 1956
The power sensitivity and the line voltage variation effects of a phase-shifting thermoregulator making use of a thermal element in a Wheatstone bridge and a grid-controlled thyratron are expressed in terms of the circuit parameters. The conditions for line voltage variation compensation are derived and the calculated results are found to be in good ...
