Abstract

We present a theoretical/experimental investigation of broadband, spatiotemporal superfocusing (SF) and field-modulation of ultrafast terahertz (THz) waves in scattering media combining the nonlinear conversion of spatially modulated ultrashort pulses with THz time-domain field detection.
