Abstract
The formation of a laser induced plasma inside a cavity was investigated and compared with laser ablation on a flat surface. It was observed that plasma temperature and electron number density both in the cavity and on the flat surface change dramatically after the laser beam reaches a threshold irradiance. As such, phase explosion was discussed to explain the large change of both plasma characteristics and mass removal when irradiance increases beyond a threshold value.
