  We review our recent results for production of $W^+ W^-$ and $t {\bar t}$
pairs via photon-photon fusion. A theoretical approach is presented in short.
We include transverse momenta of photons when calculating fluxes of photons.
Then we discuss our results for cross section (total and differential) for $W^+
W^-$ production. Results for different parametrizations of proton structure
functions are used to calculate inelastic fluxes of photons. A discussion on
rapidity gap survival probability due to remnant fragmentation is presented. A
similar discussion is presented for $t {\bar t}$ production.
