群折射率 的英文怎麼說
中文拼音 [qúnzhéshèlǜ]
群折射率
英文
group index-
We have calculated and plotted the curves of the refractive index, group velocity index, lowest - order and second - order dispersion indexes as a function of wavelength. the lowest - order and higher - order dispersion - induced broadening and deforming of light pulses is analyzed for various pulse shapes, such as gaussian, super - gaussian and hyperbolic secant pulses
給出了折射率、群速指數、低階和二階色散系數隨波長變化的關系曲線,研究了高斯脈沖、超高斯脈沖和雙曲正割脈沖等超短脈沖在clbo晶體中傳播時,由於低階色散和高階色散引起的脈沖展寬和形變。Under certain conditions, in spite of their different modal indices the two polarized components of the pulse can trap one anther and move at a common group velocity due to xpm, the phenomenon referred as self - trapping occur
在一定條件下,盡管脈沖的兩個偏振分量的模式折射率不同,但由於交叉相位調制效應,它們能相互俘獲並以共同的群速度傳輸,產生自捕獲現象。
