Abstract

We report on the formation of polarization dependent ripples on ZF(6) glass by femtosecond laser irradiation. Two kinds of polarization dependent ripples are formed on the laser modified region. The ripples with direction parallel to laser polarization distribute in a pit in the center of laser modified region, the period of the ripples increases with the increasing pulse number. The ripples with direction perpendicular to laser polarization spread around the pit, the period of the ripples (~750 nm) almost keeps constant with the increasing pulse number.

摘要

我们报道了通过飞秒激光辐照在ZF(6)玻璃上形成偏振相关的波纹。在激光改性区域形成了两种偏振相关的波纹。与激光偏振方向平行的波纹分布在激光改性区域中心的一个凹坑中，波纹的周期随着脉冲数的增加而增大。与激光偏振方向垂直的波纹在凹坑周围扩散，这些波纹的周期（约750纳米）几乎随着脉冲数的增加而保持不变。
