Abstract
The intensity of the second-harmonic emission, generated by a laser be am passing through a corona-discharge- polarized film of polyvinylacet ate doped with 4-(dimethyla,mino)-4'-nitrostilbene, was studied as a f unction of the temperature, time, degree of the free volume relaxation , and surface potential. It is established that the second harmonic in tensity decay kinetics is controlled by a decrease in the surface pote ntial with time. Relaxation of the free volume of the polymer modifies the kinetics of the surface potential, thus also affecting the second -harmonic emission intensity.
