The J-KAREN-P laser at the Kansai Photon Science Institute was irradiated to a cluster target and confirmed the second harmonic generation. Polarization measurements of the generated second harmonic revealed that the polarization plane of the component that passed through the laser-generated plasma was rotated. This result suggests that a vortex-like magnetic field centered on the laser axis is generated.
