Title (EN) LASER BEAM GENERATION APPARATUS, LASER MACHINING DEVICE, AND LASER MACHINING METHOD
(FR) APPAREIL DE GÉNÉRATION DE FAISCEAU LASER, DISPOSITIF D'USINAGE LASER ET PROCÉDÉ D'USINAGE LASER
Abstract:
(EN) A laser beam generation apparatus includes a light source section including a plurality of seed lasers each emitting laser light, an optical amplification section disposed to face the seed lasers of the light source section and configured to amplify the laser light emitted from the seed lasers and received at an incidence surface to output the amplified laser light from an emission surface, and a plurality of light-guiding paths configured to guide the laser light emitted by the seed lasers to enter the incidence surface of the optical amplification section, wherein at least one of the plurality of light-guiding paths has an optical distance different from optical distances of other light-guiding paths, wherein the optical amplification section is configured to combine the laser light from the plurality of light-guiding paths and output the combined laser light as a laser beam.
(FR) L'invention concerne un appareil de génération de faisceau laser qui comprend une section source de lumière comprenant une pluralité de lasers germes émettant chacun une lumière laser, une section d'amplification optique disposée de façon à faire face aux lasers germes de la section source de lumière et configurée pour amplifier la lumière laser émise par les lasers germes et reçue au niveau d'une surface d'incidence afin d'émettre la lumière laser amplifiée par une surface d'émission, et une pluralité de chemins de guidage de lumière configurés pour guider la lumière laser émise par les lasers germes afin que ladite lumière entre dans la surface d'incidence de la section d'amplification optique, au moins un chemin de guidage de lumière de la pluralité de chemins de guidage de lumière ayant une distance optique différente des distances optiques d'autres chemins de guidage de lumière, la section d'amplification optique étant configurée pour combiner la lumière laser provenant de la pluralité de chemins de guidage de lumière et émettre la lumière laser combinée en tant que faisceau laser.
