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).
