翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク FASOR (laser physics) ： ウィキペディア英語版 Frequency addition source of optical radiation FASOR is an acronym for frequency addition source of optical radiation. The name is used for a certain type of guide star laser deployed at US Air Force Research Laboratory facilities SOR and AMOS. Commercialization has been attempted by the company FASORtronics.〔(【引用サイトリンク】url=http://www.fasortronics.com/ )〕 The laser light is produced in a sum-frequency generation process from two solid-state laser sources that operate at different wavelengths. The ''frequencies'' of the sources add directly to a summed frequency. Thus, if the source wavelengths are $\backslash lambda\_1$ and $\backslash lambda\_2$, the resulting wavelength is :$\backslash lambda\; =\; \backslash left(\backslash frac\; +\; \backslash frac\; \backslash right)^.$ ==Application== The FASOR is used for laser guide star experiments. It is tuned to the D2a hyperfine component of the sodium D line and used to excite sodium atoms in the mesospheric upper atmosphere. The FASOR consists of two single-frequency injection-locked Nd:YAG lasers close to 1064 and 1320 nm that are both resonant in a cavity containing a lithium triborate (LBO) crystal, which sums the frequencies yielding 589.158 nm light. 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「Frequency addition source of optical radiation」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.
