Inhibition and enhancement of linear and nonlinear optical effects by conical phase front shaping for femtosecond laser material processing
Abstract The emergence of high-powered femtosecond lasers presents the opportunity for large volume processing inside of transparent materials, wherein a myriad of nonlinear optical and aberration effects typically convolves to distort the focused beam shape.In this paper, convex and concave conical phase fronts were imposed cloud19 mail on femtose
