An acceleration channel has been found in the field of a focused laser beam propagating in vacuum, which shows similar characteristics to that of a wave guide tube of conventional accelerators: a subluminous wave phase velocity in conjunction with a strong longitudinal electric field component. Relativistic electrons injected into this channel can remain synchronous with the accelerating phase for sufficiently long time and receive considerable energy from the field. We call this acceleration scheme CAS (capture and acceleration scenario). The basic conditions for CAS to occur are examined and the output properties of electrons accelerated by this scheme are also presented in this paper.
