| Abstract(in English) | The enhancement of material surface has been realized by femtosecond laser ablation. Concening BN ceramics, we have demonstrated the possibility of ablation without any evidence of melt phase and chemical composition change by non-thermal femtosecond laser ablation. Concerning the TiO_2 photocatalyst, we have demonstrated the possibility of high density drilling in a small area. This improved the photocatalytic effect of TiO_2 due to the enhancement of the surface area. Furthermore, it is shown that enhancement of the surface area is controllable by adjusting the laser fluence. |
