In this paper, we report on the demonstration of ablation processing of HAp and collagen using a high-intensity femtosecond laser with pulsewidth of 50 fs, 500 fs and 2 ps at a wavelength of 820 nm and at 1 kpps. We also address the chemical properties of the ablated surface after ablation. It is found that there is no change of the chemical content of the ablated surface before and after ablation over the pulsewidth range used in this experiment. The wide-scan XPS spectra of nonablated surface of the HAp used here.
