摘要
介绍了三种主动相位控制光纤激光相干合成方案,并分别利用这三种方案实现了3路瓦量级光纤放大器的相干合成。根据理论分析和实验研究的结果,对三种方案各自的优缺点进行了比较分析。对光纤激光相干合成在工程实际中面临的一些共性因素的影响进行了简单讨论。
Abstract
Three active phase control configurations involved in coherent beam combining of fiber lasers are introduced, and coherent beam combining of three W-level fiber amplifiers based on each phase control configuration are experimentally implemented. Comparative study and analysis on these configurations is presented based on theoretical analysis and experimental investigation. The fill factor issue involved in practical engineering is also briefly discussed.
