摘　　要：在分析具有均匀相位输出耦合器非稳腔优缺点的基础上，提出了一种改进型非稳腔。数值模拟结果表明这种非稳腔不仅克服了均匀相位输出耦合器非稳腔的缺点而且远场也有较好的聚焦能力。In this paper, based on the analysis of advantages and disadvantages of the unstable resonator with a phase-unifying output coupler, the improving unstable resonator are designed. The numericalsimulation results indicate that the improving unstable resonator overcomes disadvantages of that resonatorand its far-field intensity focusing is better than the conventional resontor.
