摘要	A solid state laser amplifier architecture in which multiple zig-zag slab laser amplifiers (50) are stacked together, side-pumped using a common pump source (52, 54), and cooled with a common cooling system. The stack of zig-zag slabs (50) produces an array of sub-beams (62) that can be combined coherently into a single composite output beam. Variations in pump power absorption through the stack are mitigated by selection of doping levels for the slabs (50). The composite output beam is sufficiently symmetrical to be directed through conventional optics of circular cross section. Multiple stacks may be arranged in a two-dimensional array to obtain even higher output powers.
其他摘要	一种固态激光放大器结构，其中多个之字形平板激光放大器（50）堆叠在一起，使用普通泵浦源（52,54）进行侧面泵浦，并用共同的冷却系统冷却。堆叠的之字形板（50）产生子束（62）阵列，其可以相干地组合成单个复合输出束。通过选择板坯（50）的掺杂水平来减轻通过堆叠的泵浦功率吸收的变化。复合输出光束足够对称，以便通过圆形横截面的传统光学器件引导。多个堆叠可以以二维阵列布置以获得甚至更高的输出功率。
主权项	A solid-state laser amplifier architecture scalable to high output powers, comprising: a plurality of slabs of solid state material having parallel side faces and configured to function as zig-zag laser amplifiers, the slabs being placed together in a stack, with gaps between adjacent side faces of the slabs; at least one source of pump power, disposed adjacent to a side face of at least one outermost slabs in the stack, to provide laser pump power to all the slabs in the stack; and a common cooling system, comprising means for containing and circulating a coolant through the gaps between adjacent side faces of the slabs, and along the side faces of the outermost slabs in the stack; wherein each of the slabs has an input end face for receiving an input beam and an output end face through which an amplified output beam is transmitted.
