Growth and Spectral Properties of Nd~(3+) Doped KLa(MoO_4)_2 Crystal

Nd3+ doped KLa(MoO4)2 single crystal with the size up to φ25 × 40 mm3 was grown by the Czochralski technique. The absorption and luminescence spectra of trivalent neodymium in KLa(MoO4)2 crystal were investigated at room temperature. The absorption and emission cross sections are 3.02 × 10–20 cm2 at 808 nm and 20.01 × 10–20 cm2 at 1061 nm, respectively. The fluo- rescence lifetime is 164 is at room temperature.
