The method of self-propagating high-temperature synthesis of submicron powders with subsequent vacuum sintering was used to produce a series of optical ceramics based on dysprosium oxide $({\mathrm{Dy}}_x{\mathrm{Y}}_{0.95-x}{\mathrm{La}}_{0.05}{)}_2{\mathrm{O}}_3$, where $x=0.7$, 0.85, and 0.9. The influence of ceramics composition on optical transmission of the obtained samples was investigated. The studied materials had several transparency windows in the visible 500–730 nm, near-IR 1900–2300 nm, and mid-IR 3500–7500 nm ranges. The dependence of the Verdet constant on wavelength in the 400–1940 nm range was measured for each ceramics composition, and analytical approximations were obtained. When Y and La dopants were used, the Verdet constant depended linearly on the concentration of ${\mathrm{Dy}}^{3+}$ ions, and its value in the visible wavelength range was about twice that of the analogous value for a terbium gallium garnet crystal. The high transmission and relatively high Verdet constant make the produced materials highly promising for fabricating Faraday devices for ${\mathrm{Tm}}^{3+}$ and ${\mathrm{Ho}}^{3+}$ lasers and for lasers emitting in the visible spectrum.

通过真空烧结获得的氧化oxide（Dy ₂ O ₃）基陶瓷的磁光法拉第效应

自蔓延高温合成亚微米粉体并随后进行真空烧结的方法被用于生产一系列基于氧化s的光学陶瓷 $（{镝}_X{\mathrm{ÿ}}_{0.95-X}{\mathrm{啦啦}}_{0.05}{）}_{\mathrm{2个}}{\mathrm{Ø}}_3$， 在哪里 $X=0.7$，0.85和0.9。研究了陶瓷组成对所得样品光透射的影响。所研究的材料在可见光500–730 nm，近红外1900–2300 nm和中红外3500–7500 nm范围内具有多个透明度窗口。测量了每种陶瓷成分的Verdet常数对400–1940 nm范围内的波长的依赖性，并获得了分析近似值。当使用Y和La掺杂剂时，Verdet常数线性依赖于Pb的浓度。${镝}^{3+}$离子，其在可见光波长范围内的值约为a镓石榴石晶体类似值的两倍。高透射率和相对较高的Verdet常数使所生产的材料极有希望用于制造用于汽车的法拉第装置${\mathrm{Tm值}}^{3+}$ 和 ${何}^{3+}$ 激光器以及用于可见光谱发射的激光器。
