Solitonic type excitations in laser- condensed matter interaction: additional proof by independent publications

摘要

The goal of this report is to discuss (in addition o 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/cm~2 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 then about micron/s. Each pulse has the following solitary wave features: 1) it is all the time of one sign, 2) its velocity U_i is nearly constant, 3) it reflects from sample surfaces without noticeable velocity change.
