The experimental setup. The system is designed for bone ablation using Er:YAG lasers (1). A plano-convex lens (3) is used for collimation, and mirrors (2, 4, and 5) are placed to redirect the beam to the sample. A plano-convex lens (6) is positioned to focus the beam onto the sample (8). A coated sapphire window (7) protects the optical components from the back. The sample is fixed on an XYZ-axis platform (9). During the ablation experiments, a water jet (10) for cooling and compressed air (11) for debris removal are positioned on either side of the sample. The sample is fixed on an XYZ-axis platform (9) during the experiments.
