Abstract

Summary form only given. Contra-directional two-beam coupling (TBC) in LiNbO/sub 3/:Fe has been a recent subject of investigation. By measuring the power of the transmitted beam, one can monitor the coupling efficiency of the PR gratings. However, repeated jumps (fast instability) in the transmitted and reflected beams have been observed and are attributed to the "quasi-breakdown" of the uniform component of the photovoltaic (PV) field., The fast instability has not previously been explored in detail.
