DEVICE FOR CONVERTING THE PROFILE OF A LASER BEAM INTO A LASER BEAM WITH A ROTATIONALLY SYMMETRICAL INTENSITY DISTRIBUTION |
摘要 |
The invention relates to a device for transforming the profile of a laser beam (5) into a laser beam (5) with a rotationally symmetrical intensity distribution such as an M-profile or a rotationally symmetrical top-hat profile, said device comprising at least one lens array (1) with at least two lenses (5) through which the laser beam (5) that is to be transformed can pass, and optical means which can direct the laser beam (5) that has passed through the at least one lens array (1) onto a working plane (3) and/or superimpose at least some sections of said laser beam on the working plane (3), the lenses (7) of the at least one lens array (1) being arranged coaxially or concentrically with respect to one another. |
