Anisotropic Filamentation of Linearly Polarized Ultra Intense Laser in Overdense Plasmas

Intense laser-driven electrostatic shocks and its acceleration of ions in overdense plasmas

We investigated numerically the formation and propagation of the electrostatic shocks in overdense plasmas irradiated by intense ultrashort laser pulses. The dependence of the initial shock speeds on the parameters of the plasma and the laser is explained by invoking the modified momentum conservation model. The acceleration of ions by the shocks is also discussed.

Filamentation instability of counterstreaming laser-driven plasmas.

Filamentation due to the growth of a Weibel-type instability was observed in the interaction of a pair of counterstreaming, ablatively driven plasma flows, in a supersonic, collisionless regime relevant to astrophysical collisionless shocks. The flows were created by irradiating a pair of opposing plastic (CH) foils with 1.8 kJ, 2-ns laser pulses on the OMEGA EP Laser System. Ultrafast laser-dr...

Study of Laser-Hole Boring into Overdense Plasmas.

Intense circularly polarized attosecond pulse generation from relativistic laser plasmas using few-cycle laser pulses.

We have investigated the polarization of attosecond light pulses generated from relativistic few-cycle laser pulse interaction with the surface of overdense plasmas using particle-in-cell simulation. Under suitable conditions, a desired polarization state of the generated attosecond pulse can be achieved by controlling the polarization of the incident laser. In particular, an elliptically polar...
