Tunable elliptically polarized Hermite-Gaussian terahertz radiation driven by two-color twisted laser pulses
We propose a scheme for tunable elliptically polarized terahertz (THz) radiation by two-color linearly polarized Laguerre-Gaussian lasers irradiating gas plasmas. Three-dimensional particle-in-cell simulations show that the field strength of THz radiation can achieve MV/cm-scale, and the radiation frequency is determined by the plasma frequency and the electron cyclotron frequency. The emitted THz radiation is Hermite-Gaussian (HG) with a broadband waveform which can be attributed to the axial magnetic fields induced by the twisted drive pulses. Meanwhile, the ellipticity of the emitted THz wave can be effectively tuned by changing the laser intensities and the extra relative phase of the two driving lasers. Thus our scheme provides an efficient and practical approach to acquire tunable HG THz radiation with elliptical polarization, which may own some novel and unique application prospects in various areas.
