A device for the conversion of laser radiation in laser radiation with a m - profile

摘要

A device for the conversion of laser radiation (21) in the laser radiation with a m - profile, comprising– Separating means (9, 34, 50), which in the operation of the apparatus the laser radiation (21) in at least two partial beams (22; 22a, 22b, 22c, 22d, 22e, 22f, 22g, 22h; 23; 23a, 23b, 23c and 23d, 23e, 23f, 23g, 23h), the at least in sections or partially in different directions or are arranged offset to one another, wherein the separating means (9, 34, 50) at least one lens array (16; 39; 41; 51a, 51b, 51c, 51d, 51e, 51f, 51g, 51h) with at least two lenses (17a, 17b; 40; 42; 52a, 52b, 52c, 52d, 52e, 52f, 52g, 52h) comprise,– an optical fiber (25), as well as– Optical means (26, 38), which in the operation of the apparatus the at least two partial beams (22; 22a, 22b, 22c, 22d, 22e, 22f, 22g, 22h; 23; 23a, 23b, 23c and 23d, 23e, 23f, 23g, 23h) in an entrance surface (53) of the optical fiber (25) introducing and / or the at least two partial beams (22; 22a, 22b, 22c, 22d, 22e, 22f, 22g, 22h; 23; 23a, 23b, 23c and 23d, 23e, 23f, 23g, 23h) in the inlet surface (53) of the optical fiber (25), at least in sections, are superimposed,characterized in that the device is designed in such a way that in the operation of the apparatus the at least two partial beams (22; 22a, 22b, 22c, 22d, 22e, 22f, 22g, 22h; 23; 23a, 23b, 23c and 23d, 23e, 23f, 23g, 23h) at least partially into the optical fiber (25) occur in which at the output of the optical fiber (25) a laser radiation with a m - profile is.
