Abstract
Upconversion lasing at 850 nm is studied in Er
+3 doped Z.B.L.A. fibers. Modelling of excited state absorption and upconversion emission from basic principles allows determining
the laser oscillation condition in the fiber. Values of excited state absorption cross-sections are deduced from laser oscillation
and spontaneous emission data and discussed.
