The DC current-voltage characteristics, induced by a driving electric field with frequency , of a one dimensional electron channel with a tunnel barrier is calculated. Electron-electron interaction of finite-range is taken into account. For intermediate interaction strengths, the non-linear differential conductance shows cusp-like minima at bias voltages integer multiples of / ethat are a consequence of the finite non-zero range of the interaction but are independent of the shape of the driving electric field. However, the frequency-scaling of the photo-induced current shows a cross-over between -1 and -2, and depends on the spatial shape of the driving field and the range of the interaction.
