Examples
- In the section 1 , we have introduced the background and the recent advance of the flattened gaussian beam ; in the section 2 , for the first time , we have calculated the type - i and type - ii shg conversion efficiency and simulated curves versus the crystal length , the pumping light polarization rate , the order of the flattened gaussian beam and the pumped power intensity , we obtain ed that the highest efficiency was influenced by the order and the polarization rate of the pumped flattened gaussian beam
从三波耦合方程及clbo晶体的光学特性出发，讨论了以平顶高斯光束入射时稳态的三波耦合方程的大信号倍频解(包括类及类相位匹配的倍频解) 。计算了其在clbo晶体上的倍频转换效率与晶体长度，基波偏振分量比，基波阶数及泵浦波强度之间的相互影响关系曲线。得出影响平顶高斯光束的最高转换效率的因素是基波的阶数n和泵浦波的偏振分量比d 。 - To accelerate the development of next generation high dwdm system , the pape r also researches the property of gain . based on optical wave nonlinear transmission equation , the gain model of fra is established . by the way of numerical analysis , it is obtained that the gain of fra has relation with pump power , input signal wave power , the effective area and absorption of fiber . the obtained conclusion has definite instruction to the design of fra
为了促进下一代超高速dwdm密集波分复用技术的发展，本文还研究了光纤喇曼放大器的增益特性，根据光波非线性传输方程建立光纤喇曼放大器增益模型，通过数值模拟分析了泵浦波功率、信号输入光功率、以及光纤有效面积和损耗对光纤喇曼放大器增益的影响，得出了一些对光纤喇曼放大器的设计有一定的指导意义的结论。 - The study of srs in non - linear optic fiber by simulink emphatically . the initial intensities of pump beam and stokes beam are similar , and small signal gain theory needs to amend have been pointed . srs comply with the special growth law , does not have " threshold " characteristics . lt depends not only on the intensity of pump beam but also on the intensity of stokes beam itself . even if the intensity of pump beam is weak , fhe srs effect is maybe still take place . in addition , the problem about srs effect depends on the number of channels , power in each channel and space of the channels , in a dwdm system has been studied
并着重论述了如何利用simulink研究非线性光纤光学中的受激喇曼效应，指出在光纤通信的情况两个光束的初始强度相差不多时，小增益理论需要修正。 srs遵从特殊的增长规律，并不具有“阈值”特性。 stokes束的增长不仅依赖于泵浦波的强度，而且也和自身的强度有关系。
