Paper Abstract

The goal of this report is to discuss (in addition to review) the independent literature works which come to our attention in 2 last years with experimental or theoretical proofs the existence of the solitonic type Wave of Change in Reflection and Conduction (WCRC). WCRC presents a new variety of transfer phenomena in condensed matter. It was excited by a single IR laser pulse with a threshold of more than 10 kW/cm2 and consists of a series of about 30 solitary pulses with propagation velocity of each subsequent pulse decreasing two times comparing with that of preceding one in the range from sound velocity to less than about micron/s. Each pulse has the following solitary wave features: (1) it is all the time of one sign, (2) its velocity Ui is nearly constant, (3) it reflects from sample surfaces without noticeable velocity change. So far the systematic WCRC study was made in Lebedev Physical Institute, grate deal in collaboration with group of Marseilles University (prof. M. Autric) and also with some others groups. Literature analysis showed independent works where WCRC can be seen and which was made in different institutions with different own goals in mind. As example, work on optical monitoring of laser damage in IR materials or thermocouple measurements of temperature non stability in water cooled copper shield stopped the high power e-beam, etc. We will discuss also some details of theoretical work connected with development of Frenkel-Kontorova (1937) topological soliton model. WCRC is rather universal phenomenon, it appears in many laser-condensed matter interactions and so it should be studied for the WCRC mechanism understanding and its effect evaluation for different applications.
