FIELD: optics.SUBSTANCE: invention relates to laser engineering and concerns monocrystalline material for disc lasers. Monocrystalline material is based on a yttrium aluminium garnet, activated by ytterbium ions. Initial components are taken in accordance with the structural formula Yb:YAlO, where- function of concentration profile change, z - axis of direction of forming the crystal concentration profile, 0<z<1.2.EFFECT: providing smoothed distribution of heat field, the absence of thermal lens inside the active element and increase of maximum size of the generated volume in the active element.1 cl, 3 dwg, 1 tbl |
