摘要：

Transient diffraction spectra and their rise and decay dynamics of a thin copper phthalocyanine film (approximate to 50 nm thickness) were investigated by femtosecond transient grating spectroscopy using a white-light continuum as a probe pulse. Temporal profiles of first- and second-order diffractions were strongly dependent on the excitation intensity, which was interpreted in terms of exciton-exciton annihilation with a time-dependent rate constant.
