Valentin A. Fabrikant: negative absorption, his 1951 patent application for amplification of electromagnetic radiation (ultraviolet, visible, infrared and radio spectral regions) and his experiments

This paper is devoted to Moscow physicist Valentin A. Fabrikant who is known for his 1939 thesis with suggestion of experiments on light amplification directly proving the existence of negative absorption in gas discharge, his 1951 patent application (jointly with M.M. Vudynsky and F.A. Butaeva) for amplification of electromagnetic radiation (ultraviolet, visible, infrared and radio spectral regions), and his experimental attempts (jointly with F.A. Butaeva) to observe light amplification in gas discharge (paper submission of December 1957)

Quantum photonics pioneering advances and emerging applications

This book brings together reviews by internationally renowed experts on quantum optics and photonics. It describes novel experiments at the limit of single photons, and presents advances in this emerging research area. It also includes reprints and historical descriptions of some of the first pioneering experiments at a single-photon level and nonlinear optics, performed before the inception of lasers and modern light detectors, often with the human eye serving as a single-photon detector. The book comprises 19 chapters, 10 of which describe modern quantum photonics results, including single-photon sources, direct measurement of the photon's spatial wave function, nonlinear interactions and non-classical light, nanophotonics for room-temperature single-photon sources, time-multiplexed methods for optical quantum information processing, the role of photon statistics in visual perception, light-by-light coherent control using metamaterials, nonlinear nanoplasmonics, nonlinear polarization optics, and ultrafast nonlinear optics in the mid-infrared

Nanodiamond Emitters of Single Photons

Luminescence properties of single color centers were studied in nanodiamonds of different origin. It was found that single photon emitters could be realized even in molecularsized diamond (less than 2 nm) capable of housing stable luminescent center “silicon-vacancy.” First results on incorporation of single-photon emitters based on luminescent nanodiamonds in plasmonic nanoantennas to enhance the photon count rate and directionality, diminish the fluorescence decay time, and provide polarization selectivity are presented

Self-focusing: Past and Present - Fundamentals and Prospects

Self-focusing has been an area of active scientific investigation for years. From a practical point of view, self-focusing effects impose a limit on the power that can be transmitted through a material medium. This book presents a comprehensive treatment of this topic and reviews both theoretical and experimental investigations of self-focusing.Self-focusing: Past and Present presents a comprehensive treatment of self-focusing and reviews both theoretical and experimental investigations of self-focusing. It connects the extensive early literature on self-focusing, filamentation, self-trapping, and collapse with more recent studies aimed at issues such as self-focusing of femtosecond pulses, white light generation, and the generation of filaments in air with lengths of more than 10 km. It also describes some modern advances in self-focusing theory including the influence of beam nonparaxiality on self-focusing collapse. In addition, this text reprints three key articles in the field, as well as the paper that describes the first laboratory observation of self-focusing phenomena with photographic evidence. Self-focusing: Past and Present is of interest to scientists and engineers working with lasers and their applications, as well as students, researchers, and laser and eye surgeons
