Popis: The quality of surface treatment of different laser materials has been studied aimed at designing composite elements. We have shown that flatness of samples should be no worse than λ/10 and roughness no more than 1.0 nm. Characteristics of ion-beam etching were found that cause no roughness degradation: Ar ions, Eion = 800 eV, and grazing angle θ = 5°. Ytterbium-doped yttrium aluminum garnet composite elements (Yb:YAG), along with a terbium gallium garnet (TGG) magnetoactive crystal with sapphire monocrystals, have been designed.
