Abstract
We have considered the problem of the growth of a bubble from a preexisting nucleation site in laser irradiated glass. We show that thermal expansion of gases inside the bubble will not give significant growth. For glass temperatures below the vaporization temperature we show that a bubble can grow by CO2 diffusion for glasses with a soda content. For glass temperatures above the vaporization temperature we examine the growth of vapor bubbles. We conclude that bubbles of several microns in size can be obtained in laser irradiated glass.
