Abstract
The quality of laser micro-machining process (micro welding, drilling, surface structuring etc…) has vital importance for electronic, aviation-aerospace and biomedical industries. Dynamics of laser- induced plasma are determined with some parameters such as laser intensity, beam waist diameter and ambient gas conditions. When the plasma density is limited with a threshold value, the laser energy can not transmitted to the material due to the rarefied plasma. This decoupling threshold has a crucial role for micro-machining operation. In the scope of this paper, the behaviour of the plasma dynamics has been examined both theoretically and experimentally for titanium material and optimal laser intensity threshold was reported to prevent dissipation of beneficial process energy and to compare numerical investigations.
