Abstract

High-energy, few-cycle THz pulse generation by high-intensity (~1018 W/cm2) femtosecond laser with plasma mirrors have received significant attention in recent years [1–3]. This novel THz source has the potential of generating large bandwidth millijoule pulse energies, opening up applications in THz nonlinear optics, single-shot imaging and spectroscopy [4]. Solid density plasma shaping has already been observed [5,6] to yield sub-cycle control in optimizing high harmonic generation from plasma mirrors. Here, we demonstrate that plasma shaping can be a prospective avenue for enhancing and controlling THz emission from plasma mirrors. In this study, we have used two different cases of plasma shaping.
