Base on the nonlinear characteristic of cold ring rolling machine's manufacturing procedure, Design the numerical real-time measurement and online control system of cold ring rolling machine.
Therefore it is necessary to investigate the influences of the facet residual reflectivity and the nonlinear polarization rotation on the characteristics of mode-locked ring lasers based on SOA.
因此，有必要对SOA的端面剩余反射率及非线性偏振旋转效应进行研究。
