Abstract
We study the influence of the transverse structure of pump and lasing field s and of the width of the doped region on the conditions for the appearance of the multimode instability in an Er3+-doped ring fiber laser. We show th at the instability can be inhibited while maintaining a large output power when the radius of the doped region is a fraction of the core radius.
