Title: 通过空气波束单次穿孔在硼硅玻璃中形成凸缘

Abstract: We demonstrate curved modifications with lengths of up to 2 mm within borosilicate glass produced by single 1030 nm picosecond laser shots with an Airy beam profile. Plasma ignition in the side lobes of the beam as well as surface damage prove to be the crucial limitations for confined bulk energy deposition on a curved trajectory. A combined experimental and numerical analysis reveals optimum laser parameters for confined bulk energy deposition. This way we achieved single pass cutting of a 525 $\mu$m thick glass sheet with a well defined convex edge down to a bending radius of 774 $\mu$m. Show Chinese abstract

Abstract: 我们展示了在硼硅玻璃中由单个1030 nm皮秒激光脉冲产生的长达2 mm的弯曲修改，其光束轮廓为Airy光束。 光束旁瓣中的等离子体点火以及表面损伤被证明是沿着弯曲轨迹进行受限体能量沉积的关键限制因素。 结合实验和数值分析揭示了受限体能量沉积的最佳激光参数。 通过这种方式，我们实现了厚度为525 $\mu$m的玻璃片单次通过切割，具有明确的凸边，弯曲半径小至774 $\mu$m。
