description Embodiments of the present disclosure include a optical assembly comprising: an axicon lens with spherical aberration configured to generate the laser beam focal line, an optical element set spaced part from the optical lens, and a focusing optical element spaced apart from the optical element set, wherein the axicon lens and the optical element set are translatable relative to each other along the laser beam propagation direction and wherein the focusing optical element is in a fixed position along the laser beam propagation direction. Des modes de réalisation de la présente divulgation comprennent un ensemble optique comprenant : une lentille axicon ayant une aberration sphérique configurée pour générer la ligne focale de faisceau laser, une partie espacée de l'ensemble d'éléments optiques à partir de la lentille optique, et un élément optique de focalisation espacé de l'ensemble d'éléments optiques, la lentille axicon et l'ensemble d'éléments optiques pouvant être déplacés l'un par rapport à l'autre le long de la direction de propagation du faisceau laser et l'élément optique de focalisation étant dans une position fixe le long de la direction de propagation du faisceau laser.
