Title

Four-photon absorption in the single-crystal polymer bis(paratoluene) sulfonate

Abstract

Strong four-photon absorption corresponding to Im[χ(7)(-ω; ω, -ω, ω, -ω, ω, -ω, ω)] has been measured for the first time to the authors' knowledge with 100-fs pulses at 1600 nm in the single-crystal polymer poly[bis(p-toluene sulfonate)] of 2,4-hexadiyne-1,6-diol. The transition involved is from the even-symmetry ground state into the vibronic subband of the dominant, even-symmetry, excited two-photon state at an energy of 2.7 eV. © 1998 Optical Society of America.
