英文摘要: To control the phase noise of two ytterbium fiber amplifiers, a coherent combination system based on an active segmented mirror (ASM) has been established in our laboratory. The ASM is controlled by a feed back control loop on the basis of a Peak Rate (PR) algorithm which is realized on a DSP + FPGA hardware control board. Experimental results indicate that when the control loop is off, the far-field interference pattern is blurred and dynamic, while when it is on, the far-field beams interference pattern achieves clear and stable. At two different output powers, the contrasts of the interference stripes are improved from 7% to 19% and 8% to 28% respectively. (C) 2008 Elsevier B.V. All rights reserved.
