Paper Abstract

In this paper, the absorption and fluorescent spectra of Nd3+: KGd(WO4)2 at room temperature were measured. According to Judd-Ofelt theory, the intensity parameters Ωλ(λ=2,4,6) were worked out. With these values, the oscillator strength, spontaneous radiative rate, branching ratio, integrated emission cross-section and laser wavelength 1.06μm emission cross-section were calculated. The energy-level of Nd3+ in KGW was given, the possibility to produce 1.33μm laser and the relationship between output and pumping power in different Nd3+ion-doped KGW were discussed.
