Laser crystal Nd:YVO4 (Neodym doped Yttrium Vanadate) is one of the most effective and advanced materials for diode pumped lasers. Nd3+:YVO4 (Neodym doped Yttrium Vanadate) lasers with green, red and blue light output are really perfect means for material processing, spectroscopy, medical diagnostics, laser printing and other applications. Compared to Nd3+:YAG and Nd3+:YLF, Nd3+:YVO4 (Neodym doped Yttrium Vanadate) diode pumped lasers have the following advantages: wide absorption bandwidth, low lasing threshold, high slope efficiency, large luminescent cross-section, linearly polarized emission and single-mode output.
