“…The filamentary structures in large-aperture optical devices have been observed in several lasers, as reviewed in [39,40], and in photorefractive crystals [28,29]. Numerical simulations have been accomplished [46]. Experimental works mainly dealt with the CO 2 lasers [39,40,47,48], dye lasers [49], and semiconductor lasers [50,51].…”

The aim of this review is twofold. First, a general approach is presented allowing for a unified description of dynamics in radiating systems of different nature. Both atomic systems as well as spin assemblies can be treated in the frame of the same mathematical method based on pseudospin (or spin) representation of evolution equations. The approach is applicable to all stages of radiation dynamics, including the most difficult initial quantum stage, where coherence is not yet developed. This makes it possible to study the process of coherent self-organization from the chaotic quantum stage. Second, the approach is illustrated by applying it for the description of several coherent phenomena. Different types of superradiance are characterized: pure superradiance, triggered superradiance, pulsing and punctuated superradiance. The theory is presented of such interesting effects as triggering dipolar waves, turbulent photon filamentation, collective liberation of light, pseudospin atomic squeezing, and operator entanglement production.

The theory of turbulent photon filamentation in lasers with high Fresnel numbers is presented. A survey of experimental observations of turbulent filamentation is given. Theoretical description is based on the method of eliminating field variables, which yields the pseudospin laser equations. These are treated by the scale separation approach, including the randomization of local fields and the method of stochastic averaging. The initial, as well as the transient and final stages of radiation dynamics are carefully analysed. The characteristics of photon filaments are obtained by involving the probabilistic approach to pattern selection.

“…Some scientists have designed and analyzed the three-dimensional large-sized axilenses or axicons with LFD function by the scalar diffraction methods [1][2][3][4][5]. Other researchers have investigated the LFD cylindrical microlenses or microlens arrays based on rigorous electromagnetic theory [6][7][8][9][10][11][12][13]. All of the previous investigations are involved with the LFD properties of lenses.…”
