Abstract:

The increase in aluminum reflectivity (280-317 nm) caused by the electric current (~ 100 MA/cm2) and XeCl laser radiation (2 MW/cm2) is investigated. The effect can be both reversible and irreversible. We suppose that this effect can be explained by partial reflection of the radiation from free electrons falling into the conduction zone of the aluminum oxide film on the metal surface during electric current and laser radiation pulses.
