Abstract
A jump in the transmittance (from to for ) of an optical gate on a Mylar film (a thin aluminium layer on a Lavsan substrate) irradiated by nanosecond pulses of a neodymium laser with an intensity up to has been recorded. The mechanism of a fast increase in the transmittance of the aluminium layer upon its overheating (without boiling) to the metal – insulator phase-transition temperature is discussed.
