| Abstract: | K_3Nd(PO_4)_2 crystal is a new high rare-earth concentration laser material. In this paper, transparent light violet single crystals, K_3Nd(PO_4)_2, were grown by the slow cooling method from a KF-KCl flux.The crystal belongs to the monoclinic system with space group P21/m, Z=2. The lattice parameters were calculated, and at the same time, the absorption, fluorescence, excitation and infrared spectra of such crystals were measured and analyzed at room temperature. |
