Peculiarities of the outside influences on all-optical poling

Abstract

The peculiarities of the outside influences on the all-optical poling process and on the formed nonlinear optical structures of second-order polarizability are studied. The basic attention is given to considering the outside influences of the laser radiations with different powers and also the variations of temperature. The observed kinetics during the outside influence in the studied phosphate glass materials was investigated and it was shown the possibility of the sufficiently increase of the photo-integrated grating structures in the all-optical poling process by means of the outside thermal influence.
