We present a theoretical prediction of a new class of unstable orbits of the equilibrium electrons in free-electron lasers, which is entirely associated with the radial self-electric field and azimuthal self-magnetic field. It is also pointed out that these self-fields may deteriorate the beam quality and thus decrease the growth rate of the free-electron laser mode.
