✦ Synopsis

This paper compares the results of experimental and theoretical studies made by the authors on high-concentration erbiumdoped fiber lasers. The studies ha¨e been made for three resonator configurations. The theoretical studies and simulations take into account both signal up-con¨ersion losses and pump-excited state absorption losses, with both losses occurring together and simultaneously at ¨arious pump powers and pump wa¨elengths. The results indicate that up-con-

## lhe combined effects of upconversion and pump excited state absorption losses on the gain from co-and contmdirectwnallypumped erbium-doped fiber amplifiers have been studied qerimentully and simulated numerically. Our results indicate that for all fiber lengths, contradirectional gain is higher
