摘要：

Thr author reports efficient upconversion optical pumping of the P-3 levels of Pr3+ in ZBLAN glass codoped with Yb3+. Measurements of Pr3+ visible emission against infrared pump intensity demonstrate thr 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 Pr3+ ions and ground-state Yb3+ ions.
