New methods for the synthesis of highly localized configurations of the optical field using coherent beam combining

Aim: to develop and study methods for creating high-intensity, sharply focused laser fields using coherent beam addition in a fiber-optical system with many channels. As one of the promising concepts on the way to creating laser systems with ultra-high peak intensity, the idea is based on the coherent addition of beams from a large number (hundreds and thousands) of fiber amplifiers of chirped pulses. This concept allows you to get a revolutionary increase in the repetition rate of super-power systems due to the efficient distribution of thermal loads, while the existing systems currently operate in a one-time or rarely periodic mode, which is associated with the fundamental difficulties of removing heat from active elements.
