We report on the usage of ultrashort laser pulses in the form of aberration-corrected Bessel-like beams for laser cutting of glass with bevels. Our approach foresees inclining the material's entrance surface with respect to the processing optics. The detailed analysis of phase distortions caused by the beam transition through the tilted glass surface allows precompensating for occurring aberrations using digital holography. We verify theoretical considerations by means of pump-probe microscopy and present high-quality edges in nonstrengthened silicate glass.
我们报告了使用像差校正的贝塞尔类超短激光脉冲进行带斜面的玻璃激光切割的情况。我们的方法是使材料的入口表面相对于加工光学器件倾斜。通过倾斜玻璃表面的光束传输引起的相位失真的详细分析允许使用数字全息术对发生的像差进行预补偿。我们通过泵浦探测显微镜验证了理论考虑，并在非强化硅酸盐玻璃中呈现出高质量的边缘。
