One of the methods is a laser-driven coil, which can generate the maximum magnetic field over 100 T by using high-power lasers whose intensity is \ (\sim 10^ {15}\) W/cm \ (^2\). A lot of research regarding magnetized HEDP physics have been investigated with the laser-driven coil target.
In the case of the laser-driven coil, as one successful example, Santos et al. (2015) measured both the magnetic fields generated by the assemblies with and without the coil wire. This method can provide the proportion of the self-generated and external magnetic fields.
In this review, we briefly introduce several approaches to generate a strong magnetic field by using high-power or high-intensity laser pulses such as spontaneous magnetic field, flux compression, laser-driven micro coils, and their applications to high-energy-density-plasma experiments.
A lot of research regarding magnetized HEDP physics have been investigated with the laser-driven coil target. The generation mechanism of such a strong field with the laser-driven coil is not completely understood yet because of the lack of experimental data.
To realize and investigate the above phenomena in the strong magnetic field experimentally, several approaches to generate the strong magnetic field over 100 T have been proposed and developed so far: pulsed-power devices, self-generated magnetic field, magnetic flux compression, laser-driven coil, and others.
One can estimate the magnetic field by measuring the polarization of a probe laser (Zhu et al. 2018; Nakamura et al. 2018). Also in this method, the crystal should be placed far from the source like the pick-up coil.
