Abstract: Many works on plasma produced by laser light in a gas or at a surface of solid have been carried out. But, plasma produced by laser light in liquid have been almost studied. The breakdown threshold of liquid plasma produced by laser light is investigated. Pure water with NaCl is irradiated by XeCl Excimer laser with the wavelength of 308nm, or YAG laser with the wavelength of 1064nm or 532nm.The absorption coefficient and focal spot size are measured, which are needed in calculating exact light intensity at focal spot. The breakdown threshold is observed. At low NaCl concentration, the breakdown threshold sharply decreases with increasing NaCl concentration. While it gradually decreases at high NaCl concentration.
