Abstract
The author has presented an overview of the ability of lepton and photon colliders to probe CP conserving and violating anomalous couplings of the top-quark. In particular, some advantages of a {gamma}{gamma} collider over the e{sup +}e{sup -} case is that the t{anti t}{gamma} three-point function can be isolated from that for t{anti t}Z, the t{anti t} production cross section is larger, and the potential for linear photon polarization provides some simple probes of CP violation. When comparison can be made, they see that both types of machines can yield comparable, if not better, constraints than those obtainable in hadronic collisions.
