摘要

本文研究了在基体中引入过渡金属对SBN晶体铁电性、光折变性和光致变色性的影响。研究了Co;Cr;Ni掺杂晶体中的二波和四波相互作用，以确定其在光信息存储和激光辐射相位共轭中的应用效率。结果表明，在掺杂Co;Cr;Ni的SBN晶体中，仅SBN:Co在线性吸收和光致吸收方面具有较强的二色性。研究了非极化SBN:Co吸收光栅的稳态和动态特性。

Growth and physical properties of photorefractive SBN single crystals, doped with Co, Cr, Ni

This paper investigated the modification of ferroelectric, photorefractive and photochromic properties of SBN crystals by means of introduction of the transition metals into the matrix. The two- and four-wave interaction in the crystals doped with Co;Cr;Ni was studied to determine the efficiency of their application in the storage of optical information and in phase conjugation of laser radiation. It was established that, of SBN crystals doped with Co;Cr;Ni, SBN:Co only is characterized by a strong dichroism in linear and photoinduced absorption. The steady-state and dynamic behavior of absorption gratings in nonpoled SBN:Co was studied.
