| 摘要 | A two-dimensional integrated laser array having a plurality of surface-emitting laser arrays and a plurality of waveguides for optically coupling the individual laser arrays together. Each surface-emitting laser array includes a plurality of injection lasers which are evanescently coupled together in order to emit a single beam of light. The coupling provided by the waveguides causes the surface-emitting laser arrays to operate in phase and at the same wavelength as an external master oscillator. Therefore, the surface-emitting laser arrays generate coherent beams of light, which are combined and focused by a micro-lens. The output of the micro-lens is a single, coherent high-power optical beam which is emitted perpendicular to the two-dimensional integrated laser array. |
| 其他摘要 | 一种二维集成激光器阵列，具有多个表面发射激光器阵列和多个波导，用于将各个激光器阵列光学耦合在一起。每个表面发射激光器阵列包括多个注入激光器，它们渐逝地耦合在一起以发射单个光束。由波导提供的耦合使得表面发射激光器阵列与外部主振荡器同相和波长相同地工作。因此，表面发射激光器阵列产生相干光束，其由微透镜组合和聚焦。微透镜的输出是单个相干高功率光束，其垂直于二维集成激光器阵列发射。 |
