Applications of the Photorefractive Effect and Damage Induced Effects in Fibers

Abstract

This focus is two-fold. One aspect concerns photoinduced effects in fibers, especially the processes of self-organized second-harmonic generation in fibers. For the most part we have developed the microscopic theory of defect formation in glass. The basic physics involved in second-harmonic generation in fibers has to led to a number other possible experiments and applications. For example it is known that a photogenerated current cannot be produced by a single optical beam illuminating a centrosymmetric medium but it is now recognized that a current can be generated in a centrosymmetric medium by illumination with two harmonically related optical fields. However, we have concluded that as an application, self-organized second-harmonic generation in fibers does not appear to be a practical means of frequency doubling conventional lasers. Thus until a conceptual or practical breakthrough occurs, we have brought to a close the experimental and theoretical work on this subject
