<p><P>PROBLEM TO BE SOLVED: To provide a method for efficiently and accurately forming a fine structure on a non-organic amorphous material, such as glass, and further to provide its usage. <P>SOLUTION: The fine structure manufacturing method for manufacturing a periodic fine structure on a transparent material by radiating an ultra-short pulse laser, such as a femto-second laser pulse, includes a step for radiating the ultra-short pulse laser so as to form filaments inside the transparent material and further to allow the filaments to arrive at the bottom portion of the transparent material. By this method, the fine structure can be efficiently and accurately formed on the transparent material, such as glass. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
