    Resumen:
    We report on growth and detailed spectroscopic study of Eu3+-doped tetragonal sodium gadolinium double tungstate, Eu:NaGd(WO4)(2), a new promising crystal for deep-red lasers. Large-volume crystal doped with 4.9 at.% Eu is grown by Czochralski method along the [001] crystallographic direction. Absorption of Eu3+ ions is studied at room temperature (RT) and at 6 K. For the absorption band related to the F-7(1) -> D-5(1) transition suitable for pumping of Eu:NaGd(WO4)(2), the maximum cross-section is sigma(abs) = 1.2 x 10(-21) cm(2) at 535.5 nm with the full width at half maximum (FWHM) of 3.1 nm (at RT, for E parallel to a polarization). For the D-5(0) -> F-7(4) transition, the maximum stimulated-emission cross-section is sigma(SE) = 1.6 x 10(-21) cm(2) at 698.3 nm (RT, E parallel to c polarization). Lifetime of the D-5(0) state is 490 +/- 10 mu s (at RT). Under UV excitation, Eu:NaGd(WO4)(2) provides intense red emission with CIE coordinates (x = 0.671, y = 0329). (C) 2016 Elsevier B.V.
