Magneto-optical properties of tellurium-arsenic-selenium glass (${{\rm Te}{20}}{{\rm As}{30}}{{\rm Se}{50}}$TeAsSe) were measured and analyzed. A Verdet constant of 15.18 rad/T/m at 1950 nm with the figure of merit of more than 8.72 rad/T, which is the highest value reported in glass materials at this wavelength, was measured. Compared to other chalcogenide glasses, such as ${{\rm Ge}{10}}{{\rm Se}{90}}$GeSe and ${{\rm Ge}{25}}{{\rm As}{15}}{{\rm S}{60}}$GeAsS, ${{\rm Te}{20}}{{\rm As}{30}}{{\rm Se}_{50}}$TeAsSe glass exhibits higher Verdet constants, broader mid-infrared transparency window, and longer infrared absorption edge, making it a very promising material to fabricate magneto-optical devices for mid-infrared applications.
对碲 - 砷 - 硒玻璃（${{\rm Te}{20}}{{\rm As}{30}}{{\rm Se}{50}}$，即TeAsSe）的磁光特性进行了测量和分析。在1950纳米波长处测得的费尔德常数为15.18弧度/特斯拉/米，品质因数超过8.72弧度/特斯拉，这是该波长下玻璃材料中报道的最高值。与其他硫属化物玻璃，如${{\rm Ge}{10}}{{\rm Se}{90}}$（GeSe）和${{\rm Ge}{25}}{{\rm As}{15}}{{\rm S}{60}}$（GeAsS）相比，${{\rm Te}{20}}{{\rm As}{30}}{{\rm Se}_{50}}$（TeAsSe）玻璃表现出更高的费尔德常数、更宽的中红外透明窗口和更长的红外吸收边缘，使其成为制造用于中红外应用的磁光器件的非常有前景的材料。
