A method for conditioning the light emission of a laser generator (1), comprising an array (2) of laser diodes positioned side by side along a spatial axis (X), to equalize brightness in the direction (X) of the array (2) and in the direction (Y) perpendicular thereto, said conditioning being such as to enable optimal use of the laser beam (L) resulting from the compounding of the individual beams (L1, L2, L3) emitted by said laser diodes, the method comprising the following steps: a) separating by deflection the laser beams (L1, L2, L3) emitted by the laser diodes; b) conveying at least the adjacent laser beams (L1, L2, L3) emitted by said laser diode array (2) into different spatial planes; c) recombining said beams (L1, L2, L3) in different planes along an axis (Y) perpendicular to the axis (X) along which the laser diodes lie; ; and d) collimating said laser beams into a resultant single laser beam (L). The method is implemented by a device comprising means for separating the individual laser beams emitted side by side by the laser diode array, and means for recombining said beams such as to superpose these latter in order to enable their subsequent collimation.

Abstract
A method for conditioning the light emission of a laser generator (1), comprising an array (2) of laser diodes positioned side by side along a spatial axis (X), to equalize brightness in the direction (X) of the array (2) and in the direction (Y) perpendicular thereto, said conditioning being such as to enable optimal use of the laser beam (L) resulting from the compounding of the individual beams (L1, L2, L3) emitted by said laser diodes, the method comprising the following steps: a) separating by deflection the laser beams (L1, L2, L3) emitted by the laser diodes; b) conveying at least the adjacent laser beams (L1, L2, L3) emitted by said laser diode array (2) into different spatial planes; c) recombining said beams (L1, L2, L3) in different planes along an axis (Y) perpendicular to the axis (X) along which the laser diodes lie; ; and d) collimating said laser beams into a resultant single laser beam (L). The method is implemented by a device comprising means for separating the individual laser beams emitted side by side by the laser diode array, and means for recombining said beams such as to superpose these latter in order to enable their subsequent collimation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
