MONOCRYSTALLINE MATERIAL WITH HETEROGENEOUS DISTRIBUTION OF OPTICAL IMPURITIES FOR ACTIVE LASER ELEMENT

摘要

FIELD: optics.SUBSTANCE: invention relates to laser engineering and concerns monocrystalline material with heterogeneous distribution of optical impurities according to a given law along the active laser element with the following structural formula:wherewhere z is a spatial coordinate directed along the length of the crystal and determining the change of Erbium and ytterbium ions concentration profile in the reference system, originating in the inlet face of the active element and having a value from 0 to 1 cm.EFFECT: high efficiency of lengthwise pumping of an active laser element.1 cl, 5 dwg, 1 tbl
