We discuss possible New Physics (NP) effects on the processes $\gamma\gamma\to W^+W^-$, $ZZ$, $Z\gamma$, $\gamma\gamma$, $HH$ which are observable in$\gamma\gamma$ collisions. Such collisions may be achieved through laserbackscattering at a high energy $e^+e^-$ linear collider. To the extent that nonew particles will be directly produced in the future colliders, it has alreadybeen emphasized that the new physics possibly hidden in the bosonicinteractions, may be represented by the seven $dim=6$ operators $\O_W$,$\O_{B\Phi}$, $\O_{W\Phi}$, $\O_{UB}$, $\O_{UW}$, $\ol{\O}_{UB}$ and$\ol{\O}_{UW}$ (the last two ones being CP-violating). In this paper, we showthat the above processes are sensitive to NP scales at the several TeV range,and we subsequently discuss the possibility to disentangle the effects of thevarious operators.Comment: 15 pages, latex file + 8 figures in ps file
