Structural influence on the femtosecond laser ability to create fluorescent patterns in silver-containing sodium-gallium phosphate glasses

Résumé

Silver containing glasses in the P2O5 - Ga2O3 - Na2O ternary diagram have been investigated to relate the effect of glass network structure and sodium ions concentration to spectroscopic and laser-writing properties of the materials. The first and most striking evidence is the large gain in the photosensitivity of fluorescent molecular silver clusters, and thus three-dimensional laser-induced patterns, from the meta-phosphate to the pyro-phosphate and ortho-phosphate glass compositions. This effect has been related to the progressive increase of the initial silver pairing quantity considering the shortening of the phosphate chains and the increase of the sodium ions concentration. One believes the presented detailed consideration of structure/property relationship will impact the design of new photosensitive glasses applied to the laser-manufacturing of components for photonic integrated circuits.
