Hybrid chemical etching of femtosecond irradiated 3D structures in fused silica glass

Autor: Roberto Osellame, Roberta Ramponi, Sara Lo Turco, K. C. Vishnubhatla

Publikováno v: MATEC Web of Conferences, Vol 8, p 05009 (2013)

We report on the fabrication of 3D micro-structures in fused silica glass using chemical etching along femtosecond laser irradiated zones. In particular, we exploited a novel approach combining two different etching agents in successive steps: the hy
