Abstract
A laser processing method comprises generating a laser beam comprising laser pulses having a duration less than 1000 ps, focussing the laser beam to form a focal region inside a transparent material and varying the position of at least one of the focal region and the transparent material so as to provide a pulse-to-pulse overlap of between 45% and 99%, thereby to form a smooth material modification inside the transparent material.
