We report on the investigations of optical and structural of ZnO films deposited by pulsed laser deposition technique on silicon (100) p-type, quartz, and glass substrates. The second order nonlinear optical response from films deposited at different ambient pressures ranging from 10 mTorr to 1 Torr of oxygen on glass substrate at room temperature depends on grain size and thickness of the film. The dependence of second harmonic generation on the size of nanocrystallites observed at different pressures is discussed.
