我们展示了一个可扩展的架构，高功率，高亮度，固态激光器的基础上的主振荡器功率放大器链的相干组合。一个共同的主振荡器注入一系列的多千瓦Nd：YAG锯齿形板条放大器。自适应光学器件校正每个放大子光束的波前。子光束被并排平铺并主动锁相以形成单个输出光束。该激光器产生19 kW的光束质量< 2X衍射极限。据我们所知，这是迄今为止最亮的连续波固体激光器。(c)2006年美国光学学会。
We demonstrate a scalable architecture for a high-power, high-brightness, solid-state laser based on coherent combinations of master oscillator power amplifier chains. A common master oscillator injects a sequence of multikilowatt Nd:YAG zigzag slab amplifiers. Adaptive optics correct the wavefront of each amplified beamlet. The beamlets are tiled side by side and actively phase locked to form a single output beam. The laser produces 19 kW with beam quality < 2X diffraction limited. To the best of our knowledge, this is the brightest cw solid-state laser demonstrated to date. (c) 2006 Optical Society of America.
