- Laser irradiation induced disintegration of a bubble in a glass melt
- Juodkazis, S.; Murazawa, N.; Wakatsuki, H.; Misawa, H.
- We report on removal of micrometer-sized bubbles from molten glass by a 1064 nm wavelength cw-laser radiation focused using an objective lens of numerical aperture 0.55. The heating of a bubble and surrounding glass by tightly focused laser beam had reduced surface tension and caused disintegration of the bubble. Disintegration occurred at typically 1850 ±50◦C. Emission of a heated gas inside the bubble was used to determine the local temperature. Temporal evolution of the bubble disintegration was imaged by a CCD camera. Physics of the interaction between a focused laser beam and bubble is discussed.
