Abstract

An optical lens is useful as a D-shape laser beam projector. The lens consists of a known linear diverging element enabling the expansion of a laser beam into an uniform line, and a matching section of an axicon, either a symmetrical half-axicon or a non-symmetrical one, cut in a plane passing through, or nearly through, its apex. The two components, joined together in a plane of cutting of the axicon section, are positioned in a laser beam such that the beam is incident on both apices of the linear diverging element and the axicon section.
