A new technology for laser cutting of glass along a curvilinear contour is described. This technology combines the use of two different methods of cutting in a single technological cycle: laser-controlled thermal splitting on rectilinear sections of the cutting contour and filamentation using a picosecond laser on curvilinear sections of the contour. The proposed technology makes it possible to significantly increase the productivity of the cutting process along curvilinear contours without compromising the strength characteristics of the glass products.

结合两种不同激光的玻璃切割技术

描述了一种沿曲线轮廓激光切割玻璃的新技术。该技术在一个技术周期中结合了两种不同的切割方法：在切割轮廓的直线部分上进行激光控制的热分裂，并在轮廓的曲线部分上使用皮秒激光进行细丝化。所提出的技术使得可以显着提高沿着曲线轮廓的切割过程的生产率，而不会损害玻璃产品的强度特性。
