    "abstract": "The tremendous applications of terahertz (THz) spectroscopy and imaging\nrequire THz sources in different parameters. We propose a novel scheme to\ngenerate single-cycle powerful THz pulses by ultrashort intense laser pulses\nincident obliquely on a tenuous plasma slab of few THz wavelengths in\nthickness. This is made possible by driving a large amplitude electron plasma\nwave in the plasma slab, thus producing a net transient current at the plasma\nsurfaces. Theory and simulations show that such a THz source is capable of\nproviding megawatt power and field strength of MV/cm, which may open up new\nhorizons for nonlinear THz science and applications.",
