Title: On a three-frequency undulator radiation

Abstract: A new undulator magnetic structure for free electron lasers is presented. For the three-frequency undulator and injection on the longitudinal axis, the trajectory of electrons is computed. This structure reduces the peak value of magnetic field component.

Key words: undulator; magnetic field; coherent radiation
