Abstract

A comprehensive overview of the phenomenology associated with the interaction of intense laser beams with matter is presented. The beam is assumed to be incident on a solid or liquid target located within a transport medium. The discussion is first categorized by the type of this medium; namely, vacuum, gas, liquid, solid or particulate. Then the dependence of the interaction is further classified by the laser flux, pulselength, wavelength and the target properties. The various classes of behavior are discussed along with the conditions for their occurrence. Classes discussed include: slow bulk heating, transparent vapor from the target surface, secondary energy transport to the ablation surface, laser absorption at the critical surface, shock induced blowoff, photoelectric cross section dependence on temperature and density, laser supported combustion and detonation, contained vaporization and Mie scattering.
