我们解释了飞秒激光辐照形成的商业冠状玻璃内部离子交换的发生和焦点周围的折射率分布。光诱导区的折射率分布呈环状，表明玻璃中发生了局部致密化。利用聚焦离子束的干法刻蚀工艺在焦点周围形成了反映密度分布的不规则表面。在飞秒激光脉冲照射下，在发生局部致密化的区域也观察到了焦点与周围区域之间的离子交换效应。(C)2008年美国物理研究所。
We explain the occurrence of ion exchange and an index profile around the focal point inside a commercial crown glass formed by femtosecond laser irradiation. The index profile in the photoinduced area has a ring-shaped pattern, which indicates that local densification occurred in the glass. An irregular surface reflecting the density distribution is formed around the focal point by dry etching process using a focused ion beam. By the irradiation of femtosecond laser pulses, the effect of ion exchange between the focal point and the surrounding area is also observed in the area in which local densification occurred.
