Nd3+ -doped LaBO2 MoO4 with noncentrosymmetric monoclinic structure is presented as a new laser crystal. By Xe-flashlamp pumping at 300 K its pulsed stimulated emission (SE) at two wavelengths of the 4F3/2 ? 4I11/2 generation channel was excited. A tentative identilication of the observed SE transitions and measurements of some spectroscopic characteristics are given. The occurrence of a structural phase transition with a large temperature hysteresis was proved by means of thermal analysis. Despite of this, large crystals of LaBO2MoO4: Nd3+ were grown by the top-seeding method. Based on its SE- and (X(2) + X(3)-active properties we classify this crystal as a promising material for self-frequency doubting and self-Raman lasers. A graph is presented.
