自由电子激光器中场量的周期倍增和混沌现象

Period- DoublingandChaotic Phenomena of FieldQuantity inAFree Electron Laser

本文用相轨道直接观察法，研究了自由电子激光器（ＦＥＬ）中场量的周期倍增与混沌现象，得到了比文献￣［１］报道的更高的周期轨道和混沌运动状态。

In this paper the period- doubling and chaotic phenomena of field quantity in a free electron laser(FEL)is discussed by the direct observation phase orbit method.Peri-od orbits higher than those reported￣[1] and the state of chaotic motion were obrerved.
