Abstract

We demonstrate a broadband terahertz (THz) time-domain system spanning 0.3-25.2 THz using N-benzyl-2-methyl-4-nitroaniline (BNA) crystals for both THz nonlinear generation and detection. Near-infrared pulses from a Yb: KGW laser are spectrally broadened and temporally compressed to 31 fs using a gas-filled singlering hollow-core photonic-crystal-fiber pulse shaper. This compact and single-color platform efficiently covers the 'new THz gap' from 5 to 15 THz, enabling sensitive and broadband spectroscopy.
