Schematic illustration of the experimental setup. DM: dichromatic mirror, CM: concave mirror, SP: spectrometer. The inset shows the output spatial profile of the TH pulse without pump.
(a) Calculated molecular alignment signals, and corresponding refractive index variations and induced spectral shifts around the half-revival times of molecular (b) , (c) , and (d) .
Measured output spectra of the probe pulses at various molecular alignment revivals of [(a)–(c)] , [(d)–(f)] , and [(g)–(i)] as labeled in Fig. 2. The solid and dashed curves represent the spectra of the probe pulse when the molecular alignment is turned on and turned off, respectively.
The output spectra of the TH pulse vs its input energy when it is tuned to match various molecular alignment revivals of . The insets show the output spatial profiles of the TH pulse at an input energy of 1 mJ.
