Abstract
Excited state absorption (ESA) has been investigated in Er3+ -doped LiNbO3 after pumping in the 4I13/2 level. Because of its long lifetime (3 ms), the 4I13/2 Er3+ ion level can show an important absorption towards higher energy levels. Especially. 4I13/2 → 4I9/2 ESA takes place not so far from the eye-safe 4I13/2 → 4I15/2 emission (maximum at 1530 nm) and can then reduce the laser performances.
