摘要
In a relativistic electron cyclotron maser with an axisymmetrical quasioptical cavity of oblique rotation at arbitrary angle,the rotating angle has a great influence on beam-wave interaction.Two different physical mechanisms are found with the rotating angle ranging from 0°to 90°.One is cyclotron auto-resonance maser regime for small angle,with small optimized external magnetic field;the other is electron cyclotron resonance maser regime for large angle,with comparatively large optimized magnetic field.
