摘要	A device for emission of laser radiation includes at least one semiconductor laser having a resonator and a pumped active zone disposed within the resonator. The zone is subdivided into at least two spatially separated active zones by free-radiation regions without lateral wave guidance. Preferably, the laser is at least two semiconductor lasers disposed in series, a row, or a line, each having an antireflection coating on at least one side. The lasers have outer mirror elements at an end of the lasers disposed in series and the outer mirror elements form the resonator. A laser configuration includes two opposite semiconductor lasers from which a fundamental mode is in each case imaged into the active zone of the opposite semiconductor laser. The laser configuration has an emerging laser beam with little divergence.
其他摘要	一种用于发射激光辐射的装置包括至少一个半导体激光器，该半导体激光器具有设置在谐振器内的谐振器和泵浦有源区。该区域通过自由辐射区域被细分为至少两个空间上分离的有源区域，而没有横向波导。优选地，激光器是至少两个串联，行或线设置的半导体激光器，每个半导体激光器在至少一侧上具有抗反射涂层。激光器在串联设置的激光器的一端具有外镜元件，外镜元件形成谐振器。激光器配置包括两个相对的半导体激光器，基本模式在每种情况下成像到相对的半导体激光器的有源区中。激光器配置具有新兴的激光束，几乎没有发散。
主权项	A device for emission of laser radiation, comprising:at least one semiconductor laser having: a resonator; and a pumped active zone disposed within said resonator, said zone being subdivided into at least two spatially separated active zones by free-radiation regions without lateral wave guidance, a respective said separated active zone appears at a sufficiently small solid angle from an opposite, further respective said separated active zone, so that higher modes of said resonator experience a smaller amplification per resonator circulation than a fundamental mode of said resonator.
