Abstract

Optical properties of undulator radiation are unique in many respects. Great enhancement in brightness and nearly perfect linear polarization on axis of mean electron trajectory, a series of quasimonochromatic odd harmonic components, axial symmetry of spectral distribution, tunabilities provided through variable field parameters, observing angles, or electron energies, and partial coherence are features to be distinguished from the synchrotron radiation from the dipole.
