Abstract
Irradiated materials that are weakly absorbing are heated by both diffusive and direct heating. This creates various internal heating patterns and introduces the possibility of developing hot spots in the specimen that are not detected by surface monitoring. These systems are investigated for a single instantaneous radiation pulse and for a chain of such pulses. Characteristic times are identified that describe various regimes in the temporal-spatial heating pattern in the specimen.
