Abstract
We have studied the Yb3+ (reversible reaction) Tm3+ nonradiative energy transfer processes responsible for population of the 1G4 thulium level under Yb3+ or Tm3+ selective laser excitation of YLF:Tm3+,Yb3+ crystal. The microparameters and the rates of the energy transfer via cross-relaxation schemes are determined. It is concluded that the process of populating the 1G4 thulium level is greatly affected by up-conversion processes not only from the 3H4 but also from the 3F4 level, proceeding within the static decay model.
