Laser beam was irradiated to water heated by the microwave, and generated bubble was observed using high speed camera. Increased frequency of bubble generation in the section including the position of laser beam irradiation was observed. At the end, although flashing occurred, there was a tendency to be delayed compared to laser non-irradiation.
