Abstract
In this paper the interaction of attosecond laser pulses with matter is investigated. The scattering and motion of heat carriers as well as the external force are considered. The heat transport is described by the thermally forced Klein-Gordon or thermal modified telegraph equation depending on the ratio of the scattering and potential motion. In the case of the thermal Heisenberg type relation V ∽ E ( is the relaxation time and V is the potential) the heat transport is described by the thermal distortionless damped wave equation. In this paper the Klein-Gordon, modified telegraph 1 equation and wave equation are solved.
期刊介绍：
Lasers in Engineering publishes original (primary) research articles, reviews, short communications and letters on all aspects relating to the application of lasers in the many different branches of engineering and related disciplines.
The topics covered by Lasers in Engineering are the use of lasers: in sensors or measuring and for mapping devices; in electrocomponent fabrication; for materials processing; as integral parts of production assemblies; within the fields of biotechnology and bioengineering; in micro- and nanofabrication; as well as the materials and processing aspects of techniques such as cutting, drilling, marking, cladding, additive manufacturing (AM), alloying, welding and surface treatment and engineering.
Lasers in Engineering presents a balanced account of future developments, fundamental aspects and industrial innovations driven by the deployment of lasers. Modern technology has a vitally important role to play in meeting the increasingly stringent demands made on material and production systems. Lasers in Engineering provides a readily accessible medium for the rapid reporting of new knowledge, and technological and scientific advances in these areas.
