PROBLEM TO BE SOLVED: To provide a liquid-phase laser ablation apparatus, little in lowering of an ablation efficiency and possible to produce a good finely pulverized particle in a stable state.;SOLUTION: The liquid-phase laser ablation apparatus has a target 25 having a component to be finely pulverized, a laser oscillating apparatus 4 discharging a target component as the finely pulverized particle in the state of an atom, molecule, ion or cluster by irradiating a laser light 5 to the target 25, and a reaction vessel 11 holding the target 25 in a liquid, wherein the reaction vessel 11 is structured so that while its inner space is divided into an ablation chamber 22 and a recovering chamber 23 by a dividing plate 21 with a flowing opening 24, the target 25 is received and held in the ablation chamber 22 and a finely-pulverizing reaction by ablation is progressed, the liquid containing the finely-pulverized particle generated by the finely-pulverizing reaction in the ablation chamber 22 is introduced into the recovering chamber 23 through the flowing opening 24 of the dividing plate 21.;COPYRIGHT: (C)2006,JPO&NCIPI
