core radius meaning in English
线芯半径
Examples
- The models ’ simulation show that single mode operate in fiber amplifier at the core radii is 32 m , when the output pulse energy is to 2 . 69mj . compared with single mode fiber amplifier , the output pulse energy is more than 2 orders
通过数值仿真,我们得到了纤芯为32 m时,放大器仍然能够保持单模运转,此时输出的单脉冲能量达到2 . 69mj ,比传统的单模光纤放大器所能提取的脉冲能量大两个量级。 - But the core and na of ld output fiber is larger than that of double cladding fiber ' s inner cladding , it is important to analyze the ray propagating and focusing . the intensity distribution of multi - mode fiber is analyzed based on our experiments . and the optimum coupling efficiency is discussed between two multi - mode fiber , especially for the condition that core radius and na of output fiber are larger than that of input fiber
接着根据输入输出光纤的纤芯直径和数值孔径的不同，分四种情况分析了两光纤之间的耦合效率，着重分析了第四种情形，给出耦合效率的数值模拟曲线，在数值计算中用到了上面得出的输出光纤端口的光强分布，最后实验验证以上的分析。
