摘　　要：基于自组织相干合成原理,在马赫-曾德复合腔中引入3dB光纤环镜为共用腔镜,低反(4.5%)布拉格光栅作为输出腔镜,获得了93.5%的相干合成效率;通过对泄漏端功率输出特性的研究,在理论和实验上研究了复合腔自组织相干的物理机制。为相干合成技术研究提供新的分析思路和更便捷的方法,并能在简单的实验设施下实现。Based on the principle of self-organization in Mach-Zehnder erbium-doped fiber laser cavity, charateristics of leak power are theoretically and experimentally demonstrated. One 3dB fiber loop mirror and a fiber Bragg grating with 4.5% reflectivity are used as cavity mirrors. A high coherent combining efficiency of 93.5% was obtained. Research on characteristics of leak power opens out self-organization mechanism in Maeh-Zehnder compound cavity. Many applications to coherent combining high power lasers are expected.
