LASER ACTIVE ELEMENT Russian patent published in 2023 - IPC H01S3/06 

FIELD: laser equipment.

SUBSTANCE: laser active element consists of at least four layers, in which areas doped with active impurity ions are located in a specific order, separated from each other with an area of undoped active impurity. A size of doped areas and order of their location inlayers is selected from conditions that, at a working level of pumping the active element, the maximum size of the bound doped area is less than a length of super-luminescence development, and doped areas in a projection to a plane perpendicular to the optical axis, along which laser radiation of the active element is formed, uniformly and fully fill the working area.

EFFECT: increase in average and pulse power of laser radiation, reduction in optical distortions occurred in an active element at powerful pulse pumping.
