Abstract
In order to make a laser cut in a diamond (1), the diamond (1) is reciprocated transversely, the radiation is focussed onto the bottom of the cut (6) by a stationary focussing lens (4 ), and the radiation is passed to the focussing lens (4) by a mirror (3) which is reciprocated in the same direction as the diamond (1), thereby rocking the axis (5) of the beam below the lens (4). This increases the energy entering the cut and reduces the focal spot area projected on the cut wall, thus increasing the energy density of radiation on the inclined cut walls.
