摘要
With recent attention to high power energy and its interaction with materials of different type,both in industry and military application,this paper covers a short review course into subject of materials response in respect to such high power energy lasers.In this paper,we are covering laser interaction with solid and going through steps of phase changes,from solid to liquid and finally vapor stage.We describe the radiation wave,propagation wave in a complex form solution,utilizing Maxwell’s equation within dielectric materials,then we look at compression of materials,due to melting and boiling driven by heat transfer energy radiation and conduction induced by these high power energy lasers such is Nd Ya and CO2 lasers with wavelengths anywhere from 1.6μm to 10.6μm.We also look at Hugoniot Elastic Limit(HEL)and spall strength of materials,with the energy lasers dueling with targeted material,where also,physics of hydrodynamics effects due to strong shock is involved.We also talk about certain available computer that allows end user to calculate these phenomena in 1-D to 3-D type scenarios.Although covering all these above issues that are very lengthy write-up proposition,we have tried to be very brief,yet to the point presentation in form of a short course in this paper.
