Abstract
The temporal shaping of femtosecond laser pulses reflected from a
one-dimensional plasmonic crystal using a commercially available polymer
grating coated with a silver film is experimentally demonstrated by time-
resolved measurements of the intensity correlation function. Shaping is
achieved by the excitation of surface plasmon-polaritons with a lifetime
comparable to the 130 fs laser pulse duration. The variety of data obtained
demonstrate the flexible shaping of fs-pulses by delaying, advancing,
splitting, broadening, compressing, and changing the topological properties
of the pulse with the plasmonic crystals under study.
