Spectroscopic studies and analysis of the laser states of Nd/3+/ in YVO4Polarized absorption and dye-laser excited fluorescence spectra of Nd/3+/ in the Y(3+) site of yttrium orthovanadate at 85 and 300 K are presented and analyzed. The absence of allowed transitions and the unusual concentration of line strength into one transition in pi polarization within a given line group is shown by the Judd-Ofelt theory to be a consequence of the D2d symmetry of the site and ion placements in the unit cell. An energy level scheme giving level positions, level identities, and observed transitions is presented. The principal laser line in this group at about 10640.9 A was found to be predominately pi polarized and to have a cross section of 30 x 10 to the 19th/sq cm, which is 4.6 times larger than the laser transition of Nd/3+/ in YAG.
