研究了激光烧蚀液体时溶解态物质向等离子体中的转移。在LiCl + NaCl水溶液中的Cu靶的激光烧蚀和等离子体的发射光谱进行。观察到Li和Na原子的发射谱线。从发射光谱估计的等离子体中的原子密度比NLi/NNa与溶液中的浓度比CLi/CNa一致。这表明，由于从目标烧蚀的极高温物质与周围的水之间的强烈相互作用，水发生了相爆炸。这导致空化气泡和溶解物质从溶液转移到气泡中，而没有任何元素选择性。
We investigate the transfer of the dissolved species into the plasma during laser ablation in liquid. Laser ablation of a Cu target in LiCl + NaCl aqueous solutions and emission spectroscopy of the plasma are performed. Emission lines of Li and Na atoms are observed. Atomic density ratio NLi/NNa in the plasma estimated from the emission spectra agrees with the concentration ratio CLi/CNa in the solutions. This suggests the phase explosion of water due to the strong interaction between the extremely high-temperature matter ablated from the target and the surrounding water. This causes a cavitation bubble and the transfer of the dissolved species from the solution into the bubble without any element selectivity.
