This paper compares the results of experimental and theoretical studies made by the authors on high‐concentration erbium‐doped fiber lasers. The studies have been made for three resonator configurations. The theoretical studies and simulations take into account both signal up‐conversion losses and pump‐excited state absorption losses, with both losses occurring together and simultaneously at various pump powers and pump wavelengths. The results indicate that up‐conversion losses are higher at longer wavelengths of 1560 nm. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 22: 119–123, 1999.
