In this work we report the upconversion processes that produce blue, green, orange, and red emission in K5Nd(MoO4)4 stiochiometric crystal together with the dynamics and spectral properties of the laser emission. It was found that upconversion energy transfer processes reduce the energy storage capacity through the reduction of the fluorescence lifetimes of the metastable 4F3/2 level. The experiments were conducted in such a way that the dynamics of the IR and visible fluorescence was performed under lasing and nonlasing conditions. The dynamics of the unconverted emission shows that both upconversion energy transfer and excited state absorption of the laser emission occur.
