Abstract
Time-resolved in-situ microscopy is used to gain insights for tailoring material modifications inside a transparent material. The types of modifications are linked to the free electron densities within the laser-induced plasma. Densities below 1019cm−3 lead to defect states and higher densities around 1020cm−3 to disruptions and cracks. In this process the plasma ignition and densification crucially depends on the pulse duration.
