Area of Modification within Transparent Materials by Femtosecond Laser

Abstract:

This paper proposes an idea for manufacturing internal patterns using a femtosecond laser. The femtosecond laser can easily be focused within transparent materials because of the advantages of multi-photon absorption and high energy density. The parameters of a femtosecond laser can be adjusted to modify the local area inside the glass and to design internal structures. The internal structures can produce optical effects. Through this process, optical plates can be manufactured in glass without wasting excess space.
