Abstract

Growth of second harmonic (SH) from 1064-nm light in optical fibers up to final efficiencies of around 1 % has been observed by several workers.1-3 We believe we are the first2 to identify the mechanism for this unusual phenomenon in terms of an optically written defect grating in the fiber with a χ(2) modulated at the phase mismatch period between pump and SH light. The orientation of the χ(2) grating is determined by the periodically reversing internal dc field that arises via a third-order nonlinear interaction between pump and SH light.3
