We report on a wide series of experiments performed with the aim of clarifying basic aspects of the interaction between short and ultrashort laser pulses and ocular media which occur in the photodisruption of ocular membranes. We performed, on a simple eye model i)the determination of the threshold intensities required for optical breakdown, and their dependence on pulse duration and geometrical conditions, with pulses ranging from the nanosecond to the picosecond regine;ii)measurements on the shielding properties of single pulses, to evaluate the intrapulse shielding, and of plasma lifetime as a means of determining possible inter-pulse shielding effect;iii)experiments to investigate the occurrence of non-linear effects like Brillouin scattering in the nanosecond regime.
