Abstract
The development of Er-doped fiber amplifiers and fiber lasers [1,2] has recently spawned interest in LiNbO3-based integrated optic versions of these devices [3,4]. Guided wave mode- locked lasers, tunable lasers, as well as traveling wave amplifiers, have been demonstrated [5,6], Er3+ doping concentrations and site distributions strongly affect the performance of these devices [4, 7], Co-doping with other rare earth ions (e.g. Yb3+) to increase the useful absorbed pump power has proven useful for fiber amplifiers and lasers [8,9], In this work we report the enhancement of the 4I13/2 level population inversion and green up-conversion of the Er ions in LiNbO3 co-doped with Yb.
