The amplitude for the reaction ..gamma gamma --> pi pi.. is calculated in a nonlocal quark model. Numerical values are found for the electric (..cap alpha../sub ..pi../) and magnetic (..beta../sub ..pi../) polarizabilities of the pions: ..cap alpha..* = 0.40..cap alpha../m/sup 3//sub ..pi../, ..beta..* = -0.39 ..cap alpha../m/sup 3//sub ..pi../, ..cap alpha..0 = 0.1..cap alpha../m/sup 3//sub ..pi../, ..beta..0 = -0.4..cap alpha../m/sup 3//sub ..pi../.
