Abstract

Transform-limited (TL) visible pulses with as short as sub-5-fs duration have been generated from a noncollinear optical parameteric amplifier and applied to the study of polyacetylene, polydiacetylene, azobenzene, and J-aggregates of porphyrin for optical devices. We also report the first direct observation of structural changes in a complex biological system, the chromophore of bacteriorihodopsin, as it undergoes the trans-cis photoisomerization by monitoring changes in the vibrational spectra of the transition state.
