  We consider the production of gravitons via two photon fusion in Kaluza-Klein
theories which allow TeV scale gravitational interactions. We find that the
processes l+ l- to l+ l- + graviton, with l=electron or muon can put quite
stringent bounds on such theories. For example, with two extra dimensions at
the Next Linear Collider with a center of mass energy of 500 (1000) GeV
attainable bounds on the scale of the gravitational interactions can reach
about 6 (9) TeV.
