High-Intensity Laser-Atom Physics

2000
Publisher Summary This chapter illustrates that the development of lasers capable of delivering short pulses of very intense radiation, over a wide frequency range, has led to the discovery of new, nonperturbative multiphoton processes in laser interactions with atomic systems.

The Physics of Intense Femtosecond Laser Filamentation

2008
When a powerful femtosecond laser pulse propagates in a transparent optical medium, be it a gas or a condensed medium, the pulse will self-focus into a series of self-foci, giving rise to the perception of a filament. This universal nonlinear propagation phenomenon is currently an interesting research topic at the forefront of applied physics and ...

Applications of Intensity Interferometry in Physics and Astronomy

Optica Acta: International Journal of Optics, 1969
Criteria as to when an intensity interferometer is competitive with a Michelson interferometer are established with the help of a simple example. There do not appear to be any cases in the field of frequency measurement where this is true. In radio astronomy it is argued that intensity interferometry might still have a role in angular measurements of ...

Forecasting Bankruptcy and Physical Default Intensity [PDF]

, 2007
This report presents two of our investigations: one is to obtain an accurate forecast for the corporate bankruptcy; the other is to obtain a physical default intensity. Both investigations were based on the hazard model, using only firm-specific accounting variables as predictors.

Fundamental Physics at the Intensity Frontier

2011
This workshop is an opportunity for the scientific community to identify the physics potential of the Intensity Frontier. Starting in September 2011, six working groups will study and begin to document the full spectrum of opportunities for fundamental physics at the Intensity Frontier and identify the necessary facilities to execute such a program ...
