Li2Tb4(MoO4)7　crystal　with　sizes　of　∅20　×　26　mm　was　grown　by　the　Czochralski　method.　X-ray　powder　diffraction　was　carried　out　and　the　lattice　parameters　were　calculated,　which　showed　that　the　single　crystal　belongs　to　tetragonal　system.　Absorption　spectrum　in　the　wavelength　range　of　400-1600　nm　and　weak　absorption　at　1064　nm　were　measured,　which　indicates　the　crystal　has　low　absorption　coefficient　at　600-1500　nm　regions.　The　Verdet　constant　of　Li2Tb　4(MoO4)7　crystal　at　532　nm　comes　up　to　-347　rad/m　T,　which　is　as　1.8　times　as　that　of　TGG　reported.　©　2012　Elsevier　B.V.　All　rights　reserved.
