Relaxed Optics: Modeling and Discussions 4

The last author book "Relaxed Optics: Modeling and Discussions 3" waspublished in Lambert Academic Publishing and Bright Sky Publisher in2024.However, author active scientific researches in this area of modernphysics for last year's allow opening and resolving some interestingproblems of Relaxed Optics. Among them are problems of coherence; laser-induced optical breakdown; laser-induced critical phenomena, includingshock processes; interference and diffraction processes; role of physical-chemical processes in the formation Nonlinear and Relaxed optical processesand phenomena; cascade processes; photon efficiency, etc.The necessity of print this book is caused of author researches in last twoyears. Results there received in the area of interference the Nonlinear Opticaland Relaxed Optical processes and phenomena or correlation betweenradiated and nonradiated second-order processes of interaction laserradiation and matter.The problems of modelling temporal hierarchic processes in NonlinearOptics and Relaxed Optics has cascade nature and only methods of RelaxedOptics allow resolving this problem with unitary point of view.
