title: [Differential spectra of hematoporphyrin in a visible area following excitation by intense subpicosecond pulse].
abstract: Difference spectra of hematoporphyrin excited by intense 300 is laser pulse were studied at various delay times. It was found that under two photon excitations very quick (approximately 1 ps) formation of photoproduct took place. Changes of the difference spectra connected with evolution of the photoproduct were observed.
