Fig. 1: The schematic of magnetized plasma rotator based on the frequency-variable Faraday rotation (FVFR) in the nonlinear plasma wake (NPW).

The rotator consists of three modules: guider, converter, and output. The yellow arrows with different lengths indicate the direction and intensity of the external magnetic field. The insets show the process of laser-gas interaction and the evolution of laser pulse in magnetized plasmas
