  The advent of a next linear $e^\pm e^-$ collider and back-scatterd laser
beams will allow the study of a vast array of high energy processes of the
Standard Model through the fusion of real and virtual photons and other gauge
bosons. As examples, I discuss virtual photon scattering $\gamma^* \gamma^* \to
X$ in the region dominated by BFKL hard Pomeron exchange and report the
predicted cross sections at present and future $e^\pm e^-$ colliders. I also
discuss exclusive $\gamma \gamma$ reactions in QCD as a measure of hadron
distribution amplitudes and a new method for measuring the anomalous magnetic
and quadrupole moments of the $W$ and $Z$ gauge bosons to high precision in
polarized electron-photon collisions.
