Photon-photon linear colliders can be realized by the laser back-scattering technique in the next-generation linear [ital e][sup +][ital e[minus]] colliders. Here the associated productions of an intermediate-mass Higgs (IMH) or [ital Z] boson with a [ital t[bar t]] pair in [gamma][gamma] collisions are studied. Since IMH is very unlikely to decay into a [ital t[bar t]] pair, [ital t[bar t]H] production is the only direct channel to probe the Higgs-top Yukawa coupling in the case of an IMH. [ital t[bar t]Z] production can be a potential background to [ital t[bar t]H] if the Higgs mass is close to [ital m][sub [ital Z]]. As an alternative to its parent [ital e][sup +][ital e[minus]] collider, [gamma][gamma][r arrow][ital t[bar t]H]([ital Z]) productions are compared with the corresponding productions in the [ital e][sup +][ital e[minus]] collisions.
