我们报告从熔融玻璃中去除微米级气泡的1064 nm波长的连续激光辐射使用数值孔径为0.55的物镜透镜聚焦。通过紧密聚焦的激光束加热气泡和周围的玻璃，降低了表面张力，导致气泡破裂。崩解通常发生在1850 +/-50 ℃。气泡内加热气体的排放被用来确定局部温度。通过CCD摄像机对气泡破裂的时间演化进行成像。讨论了聚焦激光束与气泡相互作用的物理过程。
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 50 degrees 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.
