摘要：Sm:CaNb2O6 single crystal has been grown by the Czochralski method. Its high-temperature X-ray powder diffraction, optical absorption, emission spectroscopic as well as lifetime have been studied. Thermal expansion coefficients (alpha), J-O parameters (Omega(i)), radiative lifetime (tau(rad)), branching ratios (beta) and stimulated emission cross-sections (sigma(e)) were calculated. The quantum efficiency (eta) was calculated to be 97%. The intense peak emission cross section at 610, 658 nm were calculated to be 2.40 x 10(-21), 2.42 x 10(-21) cm(2). These results indicate that Sm:CaNb2O6 crystal has potential use in visible laser and photonic devices area. (C) 2012 Elsevier B.V. All rights reserved.
