Formally, GVD is defined as the derivative of the inverse of group velocity of light in a material with respect to frequency,〔 〕〔http://www.rp-photonics.com/group_velocity_dispersion.html〕 :$\backslash textrm(\backslash nu\_0)\; \backslash equiv\; \backslash frac\; \backslash left(\; \backslash frac\; \backslash right)\_,$ where $\backslash nu$ and $\backslash nu\_0$ are frequencies, and the group velocity $v\_g(\backslash nu)$ is defined as $v\_g(\backslash nu)\; \backslash equiv\; \backslash partial\; \backslash nu\; /\; \backslash partial\; \backslash lambda^$. The units of group velocity dispersion are ()2/(), often expressed in fs2/mm. Equivalently, group velocity dispersion can be defined in terms of the medium-dependent wavenumber $\backslash lambda^(\backslash nu)$ (defined as $\backslash lambda^\; \backslash equiv\; 1/\backslash lambda$) according to :$\backslash textrm(\backslash nu\_0)\; \backslash equiv\; \backslash left(\; \backslash frac\backslash right)\_,$ or in terms of the refractive index $n(\backslash nu)$ according to :$\backslash textrm(\backslash nu\_0)\; \backslash equiv\; \backslash frac\; \backslash left(\backslash frac\backslash right)\_\; +\; \backslash frac\backslash left(\; \backslash frac\backslash right)\_.$ ==Applications== Group velocity dispersion is most commonly used to estimate the amount of chirp that will be imposed on a pulse of light after passing through a material of interest. The relevant expression is given by :$\backslash textrm\; =\; 2\; \backslash pi\; \backslash ,\; \backslash times\; \backslash ,\; (\backslash textrm)\; \backslash ,\; \backslash times\; \backslash ,\; \backslash textrm(\backslash nu\_0)\; \backslash ,\; \backslash times\; \backslash ,\; (\backslash textrm).$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Group velocity dispersion」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
