Efficient laser-overdense plasma coupling via surface plasma waves and steady magnetic field generation

Steady magnetic-field generation via surface-plasma-wave excitation.

The possibility of inducing a magnetic field via surface plasma-wave excitation is investigated with a simple nonrelativistic hydrodynamic model. A static magnetic field is predicted at the plasma surface, scaling with the square of the surface-wave field amplitude, and the influence of the electron plasma density is studied. In the case of resonant surface-wave excitation by laser this result ...

Towards efficient generation of attosecond pulses from overdense plasma targets

Theoretical studies and computer simulations predict efficient generation of attosecond electromagnetic pulses from overdense plasma targets, driven by relativistically strong laser pulses. These predictions need to be validated in time resolved experiments in order to provide a route for applications. The first available femtosecond sources for these experiments are likely to be 10 fs pulses o...

Coupling between electron plasma waves in laser–plasma interactions*

ALagrangian fluid model ~cold plasma, fixed ions! is developed for analyzing the coupling between electron plasma waves. This model shows that a small wave number electron plasma wave (v2 ,k2) will strongly affect a large wave number electron plasma wave (v1 ,k1), transferring its energy into daughter waves or sidebands at (v11nv2 ,k11nk2) in the lab frame. The accuracy of the model is checked ...
