Abstract

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, E_ion = 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.

复合光学元件设计的材料表面处理

摘要

为了设计复合元件，已经研究了不同激光材料的表面处理质量。我们已经表明，样品的平整度应不小于λ/ 10，粗糙度不大于1.0 nm。发现离子束蚀刻的特性不会引起粗糙度降低：Ar离子，E_离子 = 800 eV，掠角θ= 5°。设计了掺-钇铝石榴石复合元素（Yb：YAG），以及带有蓝宝石单晶的ter镓石榴石（TGG）磁活性晶体。
