LASER TREATMENT DEVICE AND WORKSTATION COMPRISING SUCH A DEVICE

摘要

The invention relates to a laser treatment device and a workstation comprising such a device. The laser treatment device comprises a laser head including an optical fibre terminating in a beam focusing end piece that is shaped from the free end portion (5') of the fibre so as to form a single part therewith. The device (1) is characterised in that the focusing end piece (6) is rotationally symmetrical about an axis and has a shape defined externally by a substantially semi-elliptic convex curve of given dimensions, and in that the distance d between the tip (6") of the focusing end piece (6) and the working area (9), and the shape and positioning of the end piece (6) are such that the laser head (2) generates a slightly divergent, focused laser beam in the form of a photon jet, having a diameter at the working area (9) of the order of magnitude of the wavelength.
