Abstract :
In this paper, we would like to report on the heat-affected zone of metallic bulk crystal of Cu ablated with femtosecond Ti:sapphire laser. Due to the heat effects induced by laser pulses, the ablated bottom area is partially converted into the amorphous metals from the crystalline metals. The laser-ablated area etched using argon ion etching apparatus is measured by XRD.
