Abstract :
The author reports efficient upconversion optical pumping of the 3P levels of Pr3+ in ZBLAN glass codoped with Yb 3+. Measurements of Pr3+ visible emission against infrared pump intensity demonstrate the existence of an avalanche pumping process which comprises three components: radiationless energy transfer from Yb3+ to Pr3+, excited-state absorption in Pr3+, and cross-relaxation between excited Pr 3+ ions and ground-state Yb3+ ions
