Fabrication of line- and area-type laser-induced periodic surface structures (LIPSS) induced by a flat-top beam provides improved periodic uniformity in structure compared to fabrication with a Gaussian beam. Improved periodic uniformity induces high

Transparent borosilicate glass (BK7) is extensively used in optics applications. Herein, we demonstrate that a brown-colored pattern is generated inside BK7 glass upon irradiation with a near-infrared Ti:sapphire femtosecond laser and reveal the impo
