Photoluminescent Microbit Inscripion Inside Dielectric Crystals by Ultrashort Laser Pulses for Archival Applications
Inscription of embedded photoluminescent microbits inside micromechanically positioned bulk natural diamond, LiF and CaF<sub>2</sub> crystals was performed in sub-filamentation (geometrical focusing) regime by 525 nm 0.2 ps laser pulses focused by 0.65 NA micro-objective as a function of...
