Abstract
Interaction of fundamental, second harmonic and generated static elect ric fields in Ge-doped silica fibers is considered. Frequency doubling for stationary conditions is found to be efficient only at the stage of preparation and is switched off when the fiber is full prepared. If the phase of the incident fundamental wave varies in time in a proper way (nonstationary conditions) frequency doubling becomes highly effi cient and does not decay. (C) 1998 Elsevier Science B.V.
