Abstract

The polarization and angular dependence of the light intensity threshold for generation of plasma occuring by the interaction of ruby laser radiation with gold target was investigated. These studies were conducted in vacuum using pulsed 694,3 nm radiation from the ruby laser, operating in normal and Q-switched mode. It was found, that the component of the incident electrical field normal to the metal surface generates plasma at lower intensity, than the other component, which is parallel to the surface. A possible explanation for the obtained experimental data is given.
