Beamstrahlung is the fraction energy loss to radiation as one beam pulse is accelerated by the electromagnetic field of the other pulse through which it passes in a collider. In linear colliders the individual pulses must be formed with much larger charge densities to compensate for their much lower rate of interactions (10/sup 2/ -- 10/sup 3/ per second) in comparison to storage rings (typically 10/sup 5/ per second). Therefore the electromagnetic fields generated by the charges in each pulse will be correspondingly larger, as will the acceleration they induce in the charges of the intersecting pulses; this in turn leads to a larger loss of energy to radiation. In this report we consider three questions: What is the quantum result for beamstrahlung and when is the classical result valid. How does the transverse beam geometry/emdash/i.e., ribbon versus cylindrical pulse/emdash/affect the beamstrahlung. Extending the quantum calculation to multiple photon emission, what is the photon flux and what are the prospects for a photon-photon collider. 3 refs., 2 figs.
