Abstract
Ultrashort pulse laser ablation has been investigated for noble metal targets: gold, silver and copper by use of commercially available titanium sapphire laser and chirped pulse amplifier. The pulse duration dependence of the ultrashort laser ablation characteristics in sub-picosecond regime has been shown for micro-machining application purpose. The application of two different ablation regimes is proposed. In order to know the obvious laser requirements, experimental results as well as theoretical description are discussed.
