Abstract: It is shown in works [1–5] that the electron heat transfer mechanism yields the dominating value and duration of the tensile phase in pulses of the elastic stresses excited by pulse laser heating. This leads to a nonzero average mechanical momentum and the possibility of the movement of heat conducting objects toward the pulse heat source. In this work, we present the results of an experimental study of the movement of a pendulum–an aluminum disk 20 mm in diameter and 0.85 mm thick–toward pulse laser radiation.
