Research Abstract	Magnetic ion-doped soda lime glass was irradiated with near-infrared femtosecond laser. Magnetization of irradiated glass was enhanced compared with as-prepared glass sample. We also tried to fabricate semiconductor materials using ultra-short pulse laser processing technique. By using wet-chemical-assisted femtosecond laser ablation, nano craters as small as 200nm was formed on GaN substrate.
