Zusammenfassung:	Disclosed is a laser treatment device and a workstation including such a device. The laser treatment device includes a laser head including an optical fiber terminating in a beam focusing end piece that is shaped from the free end portion of the fiber so as to form a single part therewith. The focusing end piece is rotationally symmetrical about an axis and has a shape defined externally by a substantially semi-elliptic convex curve of given dimensions, and the distance d between the tip of the focusing end piece and the working area, and the shape and positioning of the end piece are such that the laser head generates a slightly divergent, focused laser beam in the form of a photon jet, having a diameter at the working area of the order of magnitude of the wavelength.
