| Abstract: | The possibilities of occupying high-lying 4f states of Pr3+ ions in the active BaY2F8:Yb3+,Pr3+ medium according to the photon avalanche and step-by-step sensitization mechanisms are compared. It is shown that the photon
avalanche is unlikely to occur in the BaY2F8:Yb3+,Pr3+ crystal. The multiband luminescence spectra in the visible spectral range (white emission) under single- and multiwave pumping
of BaY2F8:Yb3+,Pr3+ crystal by IR laser diodes are reported. |
