  In this paper the interaction of attosecond laser pulses with matter is
investigated. The scattering and potential motion of heat carriers as well as
the external force are considered. Depending on the ratio of the scatterings
and potential motion the heat transport is described by the thermal forced
Klein-Gordon or thermal modified telegraph equation. For thermal Heisenberg
type relation V tau=hbar (tau is the relaxation time and V is the potential)
the heat transport is described by the thermal distortionless damped wave
equation. In this paper Klein-Gordon modified telegraph equation and wave
equation are solved. Key words: Attosecond laser pulses; Quantum heat transport
equation; Klein-Gordon thermal equation.
