In this paper the dynamics of the interaction of attosecond laser pulses with matter is investigated. It will be shown that the master equation: modified Klein-Gordon equation describes the propagation of the heatons. Heatons are the thermal wave packets. When the duration of the laser pulsees δt is of the order of attosecond the heaton-thermal wave packets are nondispersive objects. For δt → ∞, the heatons are damped with damping factor of the order of relaxation time for thermal processes. Key words: Temperature fields; Attosecond laser pulses; Heatons; Modified Klein-Gordon equation.
