热改性和钠钙玻璃内的元素分布进行了修改，通过在多个点的聚焦250和1 kHz的飞秒激光脉冲的平行照射。我们发现，硅分布的形状被修改和富硅层的位置取决于250和1 kHz的激光脉冲之间的相对焦点位置。我们通过垂直于激光传播轴平移玻璃样品产生一条富硅层线，证明了厚约8 μm、宽约33 μm的带状富硅玻璃的形成。此外，我们还模拟了激光辐照过程中的瞬态温度分布，并讨论了1 kHz激光辐照对元素分布的调制作用。
Thermal modification and elemental distributions inside a sodalime glass were modified by parallel irradiation with focused 250 and 1 kHz femtosecond laser pulses at multiple spots. We found that the shape of a Si distribution was modified and the position of a Si-rich layer depended on the relative focal positions between 250 and 1 kHz laser pulses. We demonstrated the formation of a ribbon-shaped Si-rich glass of about 8 μm thickness and about 33 μm width by producing a line of a Si-rich layer by translating a glass sample perpendicular to the laser propagation axis. In addition, we simulated transient temperature distribution during laser exposure and discussed the role of 1 kHz laser irradiation in the modulation of elemental distributions.
