摘要	An irradiation system includes: a first beam source configured to output a first laser beam and a second beam source configured to output a second laser beam, in which the second laser beam has a higher beam quality higher than that of the first laser beam; optics arranged to focus the first and second laser beams; and a beam guiding system including a first beam path along which the first laser beam is guided, and a second beam path along which the second laser beam is guided, in which the beam guiding system includes a beam combiner to superimpose the first and second laser beams, the first beam source is a pump laser, the second beam source is a laser resonator, and the beam guiding system further includes a beam switch adapted to feed the first laser beam into a pump laser beam path and/or into the first beam path.
其他摘要	一种照射系统，包括：第一光束源，配置为输出第一激光束;第二光束源，配置为输出第二激光束，其中第二激光束的光束质量高于第一激光束的光束质量; 光学装置，用于聚焦第一和第二激光束;和光束引导系统，包括引导第一激光束的第一光束路径，以及引导第二激光束的第二光束路径，其中光束引导系统包括用于叠加第一和第二激光器的光束组合器光束，第一光束源是泵浦激光器，第二光束源是激光谐振器，光束引导系统还包括光束开关，适于将第一激光束馈送到泵浦激光束路径和/或第一光束中。路径。
主权项	An irradiation system for a device for laser-based additive manufacturing, the system comprising: a first beam source configured to output a first laser beam and a second beam source configured to output a second laser beam, wherein the second laser beam has a beam quality higher than a beam quality of the first laser beam, a common scanner optics arranged to focus the first laser beam and the second laser beam within a manufacturing space of the device, and a beam guiding system comprising a first beam path along which the first laser beam is guided from the first beam source to the scanner optics during operation of the irradiation system, and a second beam path along which the second laser beam is guided from the second beam source to the scanner optics during operation of the irradiation system, wherein the beam guiding system further comprises a beam combiner arranged to superimpose the first beam path and the second beam path, wherein the first beam source is a pump laser, the second beam source is a laser resonator pumped by the pump laser, and the beam guiding system further comprises a beam switch arranged between the pump laser and the laser resonator and adapted to feed the first laser beam into a pump laser beam path , which extends between the beam switch and the laser resonator, and/or into the first beam path.
