This paper investigates the interaction of high intensity, circularly polarized, short laser pulses with heavy cluster plasma through analytical modeling and numerical simulations. The optimal parameters were found for the generation of several GigaGs quasi-stationary magnetic field by using the upgraded analytical model and detailed 3D PIC simulations. It is confirmed that a field of such strength slows down the thermal expansion of the cluster core in the direction transverse to the laser beam axis, which can be used in nuclear physics. The generated inward shocks produce ion core compression, which is relevant to nuclear fusion. The electrostatic interaction between the rotating laser field, electrons and ions leads to an ion spiral density distribution in the cluster's transversal plane, which is absent in a cluster irradiated by linearly polarized pulses with the same parameters.
This paper investigates how high-intensity, circularly polarized laser pulses interact with heavy cluster plasma, generating a strong magnetic field that can slow down the expansion of the cluster core and produce ion compression, which is relevant for nuclear fusion.
