Crystallization processing of glasses is important as a novel technique for the development of new optical materials, and laser-induced crystallization provides a new challenge in science and technology of materials. Nonlinear optical BaAlBO3F2 crystal lines with crossing, bending, and spiral shapes were patterned at the surface of 2NiO–49BaF2–24.5Al2O3–24.5B2O3 (mol%) and 2.9NiO–48.5BaF2–24.3Al2O...
A combination technique of Nd:YAG laser (wavelength 1064nm) irradiations and chemical etchings is applied to fabricate micro-architectures of nonlinear optical Ba 2 TiGe 2 O 8 crystal dots and lines on the glass surface, and chemical etching behaviors are examined from confocal scanning laser microscope observations. Continuous wave Nd:YAG lasers with a power of 0.85W and a...
