100-kT Magnetic field generation using paisley targets by femtosecond laser-plasma interactions

Abstract

A target using a paisley pattern generates 100-kT-level magnetic fields. Laser irradiation induces local charge separation on the target, which creates surface currents along the concave surface, generating a magnetic field. For a laser intensity of $10^{21}$ W/cm${}^2$, the target generates a 150-kT magnetic field. We developed a simple model to describe the magnetic field as a function of laser intensity and target radius. A double paisley configuration extends the lifetime of the magnetic field to the picosecond scale. The paisley design generates comparable results even if it is simplified. Thus, it is a robust and modular target suitable for magnetic field applications such as 100-kT magnetic field generation and magnetic reconnection.
