Abstract

New concept of creation of high power laser systems based on generation and amplification of radiation with controllable coherence is suggested. The performed studies demonstrate that the laser based on such a principle has a number of advantages as compared to conventional schemes of lasers (suppression of small-scaled self-focusing without application of spatial filtration, good matching of a laser-target system and control of the laser radiation intensity distribution). It was demonstrated that the laser radiation pulse may be amplified up to very high level of output laser energy density (up to 20 J/cm² at least) and transported to considerable distance without using of the traditional correcting elements (such as phase plates, spatial filters, adaptive optics, etc.). Combined with the compactness, decreasing of the requirements to precision of manufacturing of optical elements and to the room hygiene all these lead to significant reducing of the cost of the output laser energy unit.
