A typical rare gas laser that can oscillate by utilizing the population inversion that occurs between the monovalent to trivalent argon ion levels caused by electrical discharge. It can oscillate in pulses or continuous waves from the visible to ultraviolet range, but it has particularly strong oscillations at 514.5 and 488.0 nm, which are the transition lines between the 4p → 4s levels of Ar + ions. It is used as a light source for optical excitation of dye lasers, fluorescence analysis, Raman spectroscopy, holography, laser printing, color display, etc. Source: Morikita Publishing "Chemical Dictionary (2nd Edition)" Information about the Chemical Dictionary 2nd Edition |
放電によってアルゴンの1~3価のイオンの準位間で反転分布が起こるので,これを利用して発振させることのできる代表的な希ガスレーザー.可視部から紫外部でパルスおよび連続発振できるが,とくに Ar+ イオンの4p→4s準位間の遷移である514.5と488.0 nm の線が強く発振する.色素レーザーの光励起,蛍光分析やラマン分光分析,ホログラフィー,レーザー印刷,カラー表示などの光源として用いられている. 出典 森北出版「化学辞典(第2版)」化学辞典 第2版について 情報 |
