Preparation And Spectra Of Bismuth-Based Non-Linear Optical Glass

Nonlinear optical material is optical information technology, one of the key materials, in all-optical signal processing, photonic computer and so have a broad application prospects. Glass is a new type of nonlinear optical materials. Bismuth-based glass, oxide glass has a higher than normal non-linear optical coefficient, and bismuth glasses have good thermal stability, chemical stability and high visible light transmittance, and easy to control through the formation of the glass structure, the introduction of structural defects to improve its non-linear performance. So for Bismuth-based non-linear optical glass research has important theoretical significance and application value.We are in the Bi2O3 by regulating the content of the glass and found that with the Bi2O3 content increase, the glass transition temperature decreased and the refractive index and third-order nonlinear refractive index also rise, along with the glass color from yellow to red-brown, glass, With the increased absorption of light also.Our Melting Bismuth-based glass was found during the crucible of the effects of bismuth salt is bismuth glass crucible corrosion for the introduction of impurity ions, in the same melting temperature, the use of corundum pot can increase resistance of glass crystallization stability and transmission, the glass on the platinum crucible corrosion serious, especially the platinum particles by glass corrosion in glass solution, it was very easy to form nano-particles or a family reunion into a gel particle dispersion in the glass to form the source to deepen the color of glass to reduce glass transmittance.In this article, through the glass of the nature of computing and non-linear formula to calculate the Bismuth-based linear and nonlinear refractive index of glass...
