Book excerpt: The authors study the processes[gamma]e[r[underscore]arrow][gamma]e and[gamma][gamma][r[underscore]arrow][gamma][gamma], in the context of the proposal for Weak Scale Quantum Gravity (WSQG) with large extra dimensions. With an ultraviolet cutoff M[sub S][approximately] 1 TeV for the effective gravity theory, the cross sections obtained for these processes at the Next Linear Collider (NLC), with the e[gamma] an[gamma][gamma] options, deviate from the predictions of the Standard Model significantly. The results suggest that, for typical proposed NLC energies and luminosities, the predictions of WSQG can be tested in the range 1 TeV[approx[underscore]lt] M[sub S][approx[underscore]lt] 10 TeV, making e[gamma] an[gamma][gamma] colliders important tools for probing WSQG.
