For the next generation of {ital e}{sup +}{ital e{minus}} linear colliders in the TeV range, the energy loss due to {ital beamstrahlung} during the collision of the {ital e}{sup +}{ital e{minus}} beams is expected to be substantial. One consequence is that the center-of-mass energy between the colliding particles can be largely degraded from the designed value. The knowledge on the differential luminosity as a function of the center-of-mass energy is essential for particle physics analysis on the interesting events. On the other hand, the beamstrahlung photon spectrum provides useful information on the low-energy backgrounds and high-energy {gamma}{gamma} luminosity. In this paper, we derive analytic formulas for the {ital e}{sup +}{ital e{minus}} and {gamma} energy spectra under multiple beamstrahlung process, and the {ital e}{sup +}{ital e{minus}} and {gamma}{gamma} differential luminosities. Major characteristics of these formulas are discussed.
