摘要: 離子通道激光(ICL)是一種可工作在紫外和X射線區(qū)的新型自由電子激光。本文對(duì)低增益情況下ICL的輻射放大機(jī)制進(jìn)行了研究。利用Madey理論導(dǎo)出了ICL的增益公式;通過群聚參量Bi對(duì)ICL中電子的兩種不同的群聚機(jī)制進(jìn)行了討論;由諧振條件得出了ICL的輸出頻率,并與回旋自諧振脈塞(CARM)和常規(guī)自由電子激光(FEL)進(jìn)行了比較。

Abstract: Ion-channel laser (ICL) is a new form of free electron laser which can produce tunable-coherent radiation with frequencies ranging from microwave to soft X rays. In this paper, the amplification mechanism of ICL in low gain regime is investigated. Using the Madey theory, the gain formula of ICL is derived. Two different bunching mechanism of the electrons in ICL are discussed through the bunching parameter Bi. The output frequency of ICL is obtained from the resonance condition, and the comparison is carrying out among ICL Cyclotron Auto Resonance Maser (CARM) and conventional Free Electron Laser (FEL). -
