Research Abstract

The precise measurement for crystaldegree was performed on cupper thin film with transmission electron microscope. We have analyzed the electron diffraction patterns in the laser fluence of 0.08 -0.64 J/cm2where the grating structure is formed on thin films. It is found that the crystal structures are transformed depending on laser fluence; polycrystalline structures at <0.2 J/cm2, amorphous at ~ 0.23 J/cm2, and polycrystalline structures again at > 0.35 J/cm2. The mechanism of crystal structure transformation by femtosecond laser pulses is conceptually proposed, that is induced by the injection of energetic ions generated in the process of self-formation of periodic structures.
