This proposal aims at measuring the local residual stresses and eventual defect densities as a function of the distance from the milling process using Laue-DIC with increased resolution in order to quantify the impact of femtosecond laser milling parameters on the milled surface. To do so, we will use the LaueMAX station at BM32/IF beamline with a 0.3 µm² spot size to scan in 2D multiple samples. We want to further explore the unique lateral and strain resolution of Laue DIC and extent this study to metal and ceramic base materials to optimize milling parameters such as fluence, speed or the number of repeats to reduce the induced residual strains. Collected data will be analyzed in line with the different parameters used for milling. Complementary cross-sectional FIB/SEM investigations will also be done after the experiment to illustrate the importance of the redeposition layer created during the milling process.
