In this paper, a new type of laser crystal Nd 3+: NaY (WO 4) 2 has been reported. Its structure, fluorescence spectrum and absorption spectrum were measured. With φ3mm × 25mm2 small pulse lamp pumped φ3mm × 5.95mm2 laser rod, get 22.5mJ laser energy output, good physicochemical properties, is a good prospect for the application of laser crystals.
