Resumen: We report on the crystal growth, structural and spectroscopic investigation of a novel trigonal calcium vanadate crystal, Tm3+:Ca9La(VO4)(7). Polarized absorption, stimulated-emission and gain cross-section spectra are determined for this material. The maximum sigma(SE) corresponding to the F-3(4) -> H-3(6) transition amounts to 1.28 x 10(-20) cm(2) at 1854 nm for sigma-polarization. The measured lifetime of the Tm3+ ions in the F-3(4) state is 1.19 ms. The Judd-Ofelt analysis performed yielded intensity parameters of Omega(2) = 4.682, Omega(4) = 0.659 and Omega(6) = 0.475 [10(-20) cm(2)]. The polarized Raman spectra indicate a strong and broad band centered at 867 cm(-1). Owing to the disordered nature of Ca9La(VO4)(7), the Tm3+ ions exhibit a broad and smooth gain profile at similar to 2 mu m. The spectroscopic properties of Tm3+:Ca9La(VO4)(7) are very promising for broadly tunable and ultrashort pulse lasers near 2 mu m. (C) 2017 Optical Society of America
