Abstract : The report is devoted to solid-state lasers, which are based upon balanced and semi-classical equations and also equations of quantum electrodynamics. Various types of solid-state lasers and amplifiers and dependences of their output characteristics on parameters of an active medium, resonator, pumping and others are examined. Much attention is given to the nonstationary process of generation and amplification. Limiting characteristics of lasers are determined. Results of the most interesting experimental investigations are given. Properties of various crystals and glasses, which are used as active media, are discussed. Spectra of their absorption and radiation, fundamental characteristics of energy levels, probabilities of transitions, and some temperature dependences are examined. Various methods of the excitation of optical generators and pumping systems which provide the effective transmission of exciting radiation into active specimens, are examined. Fundamental questions of the theory of optical resonators are discussed. The structure of their types of oscillations, their resonance frequencies, and quality factor are given. Feasible methods of the selection of types of oscillations in optical generators are considered. (Author)
