Abstract (EN): Thin films of indocyanine green J-aggregates in polymers have been prepared and their saturable absorption properties studied in a high intensity regime using a unique ultrashort pulse Ti:sapphire laser (10 fs) with a very broad bandwidth (over 200 nm at -20 dB). The samples showed a surprisingly high stability to irradiation, strong absorption bleaching, and wavelength dependent differential absorption spectra.
