Abstract

Interaction of laser radiation with solid targets - actively developing area of modern researches. But the processes occurring on the backside of a sample are little investigated. It is revealed with the help of tunnel microscopy methods, that on the surface of Cu, Au, Mo, Pd, W and of some other metals are formed defects looking like prismatic holes with strictly certain corners and linear sizes ~10 nm at any way of loading. It is investigated kinetics of the sizes growth, accumulation and destruction of the defects. It is found, that such defects as microcracks, porous and lines of sliding are formed at superposition of prismatic defects. Operation with a laser pulse has allowed: to choose the value of the energy entered into a sample, with the good accuracy to register the beginning and the end of input of energy, to locate a place of input, to calculate temperature and pressure increasing. Thickness of samples and energy of the laser pulse got out such: the tunnel microscope have to register changes of nanorelief on the backside in absence of a plasma fuel on irradiated - the frontal side of a sample. It has provided an opportunity to compare received nanorelief topograms of the back surface, to investigate cyclic regime and also to count up quantity of new appearing defects on topograms of a surface. It for the first time has allowed to establish interrelation between change of the nanorelief of the back surface, caused by the exit of dislocations on the surface and number of laser pulses irradiated on the frontal side. That essentially opens an opportunity of management and formation of the given roughness of a metal surface.
