Abstract: 

Yttrium-aluminum garnet crystals doped by samarium ions (YAG:Sm) were grown by the method of horizontal directional crystallization in molybdenum crucible in reducing carbon-containing medium Ar+(CO, H2). Studied were the content and distribution of Sm3+ ions, the spectral, structural characteristics and the main types of defects of these single crystals. There was shown the possibility to obtain YAG:Sm crystals of optical quality with the concentration of samarium ions up to 7. 4 at. %, as well as the coefficient of linear optical absorption equal to 0.015 cm-1 and 6 cm-1 for the pumping and generation wavelengths of YAG:Nd crystals, respectively. Established was the existence of additional absorption bands in the UV and visible ranges caused by the reducing crystal growth conditions and formation of F+- color centers.
