(Color online) Schematic illustration of the experimental setup. Linearly chirped pulses were spatially overlapped with a varied time delay through a homemade Gires-Tournois etalon, and the intensity front was tilted through a grating-lens combination. A transform limited readout pulse was used to measure the THz field profile through electro-optic sampling and also to measure the chirp-and-delay optical waveform through cross-correlation. λ/2, half waveplate; λ/4, quarter waveplate; P, polarizer; OPM, off-axis parabolic mirror; PD, photodiode; and WP, wollaston prism.
(Color online) Third-order cross-correlation measurement between the chirp-and-delay etalon output and a transform limited readout pulse through optical Kerr effect in silica glass. The Fourier spectrum of the intensity modulations is shown in the inset.
(Color online) (a) THz field traces measured through electro-optic sampling and (b) the normalized Fourier spectra, generated with 6 mJ near-infrared chirp-and-delay tilted intensity front waveforms at 1 kHz repetition rate.
(Color online) A THz field trace measured through electro-optic sampling and the normalized Fourier spectrum, generated with a 35 mJ near-infrared chirp-and-delay tilted intensity front waveform at 10 Hz repetition rate.
