Secondly, based on the analysis of the relationship between the processing tasks, a hybrid algorithm combined the filtered beam search algorithm with the local search algorithm is proposed.

其次，在对工序任务之间的逻辑关系深入分析的基础上，提出一种基于过滤束算法思想与基本邻域搜索算法相结合的混合算法。

In order to raise the couple efficiency of pumping double cladding fiber laser, the beam is reshaped with rectangular prisms, spatial filtered and focused with aspheric lens.

为了提高双包层光纤激光器泵浦光的耦合效率，对泵浦光采用直角棱镜组进行了光束整形、空间滤波、非球面镜聚焦。

One way to improve beam quality is that the frequency having high nonlinear gain should be filtered by spatial filter pinhole.

改善的方法之一就是利用空间滤波器小孔将非线性增长很快的部分滤掉。
