Confocal microscopy was employed to evaluate the surface morphology of the fabricated samples in greater detail. This technique allowed for high-resolution, three-dimensional imaging of the sample surfaces, providing precise information on surface texture, depth profiles, and topographical variations. By capturing optical slices at different depths, confocal microscopy enabled accurate reconstruction of the surface structure, which was essential for assessing the quality and uniformity of the laser-processed areas. The data obtained supported the refinement of processing parameters and helped ensure consistency across different samples.
