[en] A numerical study of spatial and temporal dynamics of nonlinear absorption coefficients of laser-induced plasma in distilled water was conducted using a nonlinear time- and space-dependent model. By taking into account the transient nature of the plasma as well as changes of the intensity-dependent refractive index of liquid water, it was evaluated the time–space-dependent absorption coefficient of the plasma for laser pulses of 30-ps, 1064-nm at focusing angles between 4° and 28° and energies in the wide range of 0.1–800 μJ. In this study, the simultaneous effects of the main mechanisms of ionization including multiphoton and cascade ionization, self-focusing, and plasma-defocusing were considered on the spatio-temporal dynamics of the plasma absorption coefficients using a paraxial-ray-tracing procedure. The results of the simulation and the reported data from other studies showed a qualitatively similar trend in the average plasma absorption coefficients. It was observed that the normalized energy for which the largest absorption coefficient of the laser-induced plasma was obtained is roughly independent of the radiation angle. It was also found that the ratio of the distance to the focal point of a region of plasma, where the largest absorption coefficient occurs, to the Rayleigh length is almost identical at all the angles of radiation. The outcomes of this study can be further used in time-based models describing the laser interaction with aqueous media such as biological tissues to account for the plasma formation effects on the propagating laser pulse.
