Abstract
We report on the fabrication of hollow microfluidic channels with a circular cross-sectional shape embedded in fused silica by spatiotemporally focusing the femtosecond laser beam. We demonstrate both theoretically and experimentally that the spatiotemporal focusing of femtosecond laser beam allows for the creation of a three-dimensionally symmetric spherical intensity distribution at the focal spot.
摘要
我们报告了通过时空聚焦飞秒激光束在熔融石英中制造具有圆形横截面的空心微流道的方法。我们从理论和实验上证明了飞秒激光束的时空聚焦可以在焦点处产生三维对称的球形强度分布。
