The progression of high-power laser systems gave rise to several concepts of their advent. There are laser systems in which the population inversion is made by thermal pumping (gasdynamic lasers), by chemical reactions (chemical lasers) and by electrical discharge (electric-discharge lasers) or by using their combination. To maintain high-power radiation in the continuous regime, gas flow is used in all lasers. Among there is also idea of creation of electrogasdynamic CO combustion-product laser in using air as buffer gas with demonstrating lasing on the small-scale model system. A multipurpose self-contained laser system of high power with electrogasdynamic CO combustion-product lasers are proposed. For economical and ecological reasons the gasdynamic and chemical lasers are practically unacceptable in industrial applications. Therefore, the proposed electrogasdynamic CO laser is preferable. Determination of efficiency of high- power laser in the industry and optimization its parameters require the formation of particular task. However, at the present time high-power lasers expect only the fields of their application. Widespread use of high-power lasers in the industry is impossible because of limits of existing in high-power lasers, high cost of laser energy production and laser itself. The object of this work is a design of general conception of creating high-power industrial lasers by generalizing results of works. It is allowed to define the ways of their advent and the fields of application and to solve the problem of high-power industrial laser's creation. This problem arose in appearing first lasers. In this case, the fields of application, which are required small powers, are not considered. For example, holography, survey, communications, medicine, etc., do not impose high requirements to power quantity and laser efficiency.
