Laser-induced structural modification in calcium aluminosilicate glasses using molecular dynamic simulations.

Glass structures of multicomponent oxide systems (CaO-AlO-SiO) are studied using a simulated pulsed laser with molecular dynamics. The short- and intermediate-range order structures revealed a direct correlation between the transformation of Al to Al, regions of increased density following laser processing, inherent reduction in the average T-O-T (T = Al, Si) angle, and associated elongation of the T-O bonding distance. Variable laser pulse energies were simulated across calcium aluminosilicate glasses with high silica content (50-80%) to identify densification trends attributed to composition and laser energy.
