Abstract
The nonlinear non-radiative interaction processes lead both to up-conversion of excitation and population of the upper-lying levels, and to the luminescence quenching nonlinear with respect to the excitation intensity. As is evident in this case, a change in the decay kinetics of the given term should be observed. Besides, the probabilities of nonlinear non-radiative interaction depend on the concentration of excited ions. In this work we considered the prospects of development of the visible and IR laser-diode pumped lasers based on TR3+-doped double-fluoride crystals. The luminescence spectra of Er ions in LiYF4 (YLF) crystals were recorded at the up-conversion pumping at different temperatures, the mechanisms of the inverse population of the laser levels produced with selective IR pumping are discussed.
