- Аннотация: Thulium-doped magnesium molybdate single-crystal (Tm3+:MgMoO4) was grown by the Czochralski method(melting point: 1322 ◦C). The actual Tm3+ doping level was measured to be 0.1 at.% (the segregation coefficientwas only 0.02). Tm:MgMoO4 belongs to the monoclinic class (sp. gr. C2/m, lattice constants: a = 10.2769(2) Å, b= 9.2898(5) Å, c = 7.0269(4) Å, β = 106.898(6)◦). The thermal expansion tensor of this crystal is determined. Itsthermal conductivity is also measured at 50–300 K (at room temperature, it amounts to 2.64 Wm 1K 1).Polarized Raman spectra are presented and the strongest mode is found at 957 cm 1. Optical spectroscopy ofTm3+ ions is studied indicating broad emission bands extending beyond 2 μm (the 3F4 → 3H6 transition) and along lifetime of the 3F4 excited-state (1.972 ms). This makes Tm:MgMoO4 promising for broadly tunable andmode-locked lasers, when the technological problem of fabricating crystals with higher Tm3+ concentrations willbe solved.
