Abstract
Growth and collapse motion of a hemispherical cavitation bubble, produced by a giant-pulsed laser beam irradiation forcusing on a solid boundary, and pressure waveform near the bubble are examined in detail by a high-speed photography and others. They are compared with the results of a himispherical bubble on a solid boundary, produced by an electric discharge in water. The experimental results are elucidated by a numerical analysis of a cavitation bubble model. Thus, the characteristics of a hemispherical cavitation bubble, produced by a laser irradiation, that so-called microjet and impulsive pressure like a shock wave are not detected at its collapsing stage, are revealed.
