In this paper, the trajectory as well as the temporal and spatial characteristics of the electromagnetic radiation of high-energy electrons collided by fields of relativistically circularly polarized laser pulses are studied theoretically and calculated numerically, based on Lorentz equation, energy equation of electrons, and the basic equations of electron radiation. Results shows that the head-on collision of a single counter-streaming electron and an intense circularly polarized laser pulse can produce an ultra-intense pulse with zeptosecond duration in the direction where the azimuth angle ##IMG## [http://ej.iop.org/images/1555-6611/30/11/115301/lpabb6e5ieqn1.gif] {$\phi = {\rm{ }}0^\circ $} and the polar angle ##IMG## [http://ej.iop.org/images/1555-6611/30/11/115301/lpabb6e5ieqn2.gif] {$\theta {\text{ = 90}}^\circ $} .
