Laser-induced and space-selective crystallization of yttrium aluminum garnet crystal from SiO₂/Al₂O₃/Y₂O₃/KF/Na₂O/AlF₃/B₂O₃ glass system

Abstract

Femtosecond laser-induced crystallization in glasses is of interest because of its significant applications in optics and photonics.

Anisotropic crystallization of YAG on the surface of glass by CO2 laser irradiation

“…This conclusion was supported by earlier works that utilized a dynamic inscription of the femtosecond laser on the surface of the glass, where the top layer was composed of a segmented-denser YAG crystals and the second layer was composed of the lower condensed crystals that were grown from the first layer toward the inner bulk of glass. 15…”
