Paper Abstract

In this work, together with the laser dynamics and for the first time, the study of upconversion processes that produce violet and visible emissions in yttrofluorite mixed crystals with 15 wt% of YF3, and 1, 4, 8, and 16 wt% of NdF3 is presented. Site-selective excitation of Nd-doped yttrofluorite crystals by using spectrally narrow pump pulses have shown that it is possible to lase these materials in a single line at 1054 nm or at 1063 nm independently, or simultaneously in both lines depending on the Nd3+ concentration and the excitation wavelength. The upconversion measurements were conducted in such a way that the dynamics of the violet and visible fluorescence was performed under lasing and nonlasing conditions. The dynamics of the upconverted emission shows that both energy transfer upconversion and excited state absorption of the laser emission occur.
