One way to improve beam quality is that the frequency having high nonlineargain 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。

The control of nonlineargain for interaction between solitons has been studied by numerical analysis in band-limited amplification propagation system.
应用数值分析方法研究了带宽限制放大传输系统中非线性增益对孤子间相互作用的控制作用。

The nonlineargain and the impulse response functions of linear subsystem be obtained by using the step-changeds and cyclic impulse with different amplitudes as input signals.
