Abstract
Observation of the front and rear plasma expansions from a laser‐irradiated thin film has been used to study the thermal conduction of polystyrene targets. The existence of reduced conductivity has been inferred above a threshold of 1014 W/cm2. The percentage of laser radiation transmitted through the thin film decreased by an order of magnitude as the laser flux increased from 1013 to 1014 W/cm2.Keywords
