Transient absorption spectroscopy and two-photon fluorescence techniques were used to study the nonresonant optical nonlinearities in poly(pphenylenevinylene) (PPV) and its phenyl substituted derivative (PPPV). Strong two-photon absorption with a coefficient /I in the range of 5 cm/GW was found. The

We report the two-photon fluorescence excitation spectrum of poly(pphenylenevinylene) over the energy range 1.1-2.0 eV. The onset for two-photon fluorescence excitation is at 1.3 eV with a strong peak near I.475 eV. The peak locates the energy of the lowest even parity excited singlet at 2.95 eV, so
It has been found that higher excited states, populated by two-photon absorption, ionize with an effkiency which, in the energy range of 5.3-6.4 eV, is independent of the energy of the excitation. This behavior is similar to that observed in sequential twostep excitation (exciton photoionization) an
All (twelve) optical diffuse interstellar absorption bands appearing in the interval 768.0-788.0 nm are assigned on the basis of a nonlinear effect: Lyman-alpha-driven, resonantly enhanced two-photon absorption by hydrogen molecules located near H II regions of young, hot stars.
