Intense laser irradiation to liquids can induce morphological changes such as cavitation, plume ejection, and so on with a distinct laser fluence threshold. Intense UV laser excitation of organic liquids generating dense electronically excited states of liquid molecules also leads to morphological changes, which is termed as liquid ablation. In this review of Part II, mechanisms and dynamics of the liquid ablation are considered on the basis of experimental results of nanosecond time-resolved imaging and spectroscopy. In case of organic solutions of aromatic molecules, photothermal processes such as explosive boiling are dominant, while photochemical fragmentation reactions play a key role in the ablation of neat benzene and related derivatives.
