Abstract

Femtosecond laser micromachining on back surface have been investigated experimentally using simultaneously spatially and temporally focused (SSTF) vortex beams. Uniform ring-shape ablations have been made on back surface of borosilicate glass. The feasibility of laser micromachining using femtosecond SSTF vortex beam has been demonstrated.
