    Abstract: The invention describes a laser device (100) enabling controlled emission of individual laser beams (194). The laser device (100) comprises an optically pumped extended cavity laser with one gain element whereby a multitude of pump lasers (110) are provided in order to generate independent pump beams (191) and thus corresponding laser beams (194). The laser device (100) may be used to enable simplified or improved laser systems (500) as, for example, two or three-dimensional laser printers. The pump laser (110) may be VCSEL and the laser (160) may be a VECSEL monolithically integrated with the pump VCSEL array on the same substrate. Pump mirrors (140) and external cavity mirror (150) may be integrated into a single optical reflector with regions having different curvature. The laser emission is controlled by the pump light, i.e. transversal shape of the laser beam and/or number of laser beams is controlled by switching on/off the individual pump lasers (110).

    Abstract translation: 本发明描述了能够控制发射各个激光束(194)的激光装置(100)。 激光装置(100)包括具有一个增益元件的光泵浦扩展腔激光器,由此提供多个泵浦激光器(110),以便产生独立的泵浦光束(191)并因此产生相应的激光束(194)。 激光装置(100)可用于使简化或改进的激光系统(500)例如为二维或三维激光打印机。 泵激光器(110)可以是VCSEL,并且激光器(160)可以是与同一衬底上的泵浦VCSEL阵列单片集成的VECSEL。 泵反射镜(140)和外腔镜(150)可以集成到具有不同曲率的区域的单个光学反射器中。 激光发射由泵浦光控制,即激光束的横向形状和/或通过接通/关闭各个泵浦激光器(110)来控制激光束的数量。
