We demonstrate the possibility to modify dielectric materials (borosilicate glass) surface and volume using tightly focused femtosecond vortex beams (with different topological charge m = 1; m = 2; m = 3; m = 5; m = 10; m = 25) formed by computer generated amplitude holograms. By controlling femtosecond vortex beam (λ=1030 nm) waist position [...]z, number of incident pulses N, topological charge m and pulse energy Ep we get different structures induced: from micron-size ring-shaped to nanosized structures. |
