Diode-pumping with appropriately modulated pulses is used to expose subtle input / output pulse-timing characteristics of Er3+:Yb3+-codoped systems, particularly Er3+:Yb3+:glass and Er3+:Yb3+:YAG, and study their relation to laser efficiency. In free-running operation, these systems may persist to lase for uncommonly long time periods (up to a ms) after the pump stops. In Q-switched operation, maximum laser output is obtained only if Q-switching is purposely delayed for some significant additional time (typically 50-500μs) following the end of the pump pulse. Furthermore, pump-pulse duration affects profoundly the Er3+:Yb3+-laser output performance, especially in Q-switched mode. Numerical modeling simulations are presented, accounting for the observed effects and extrapolating them to novel regimes of Er3+:Yb3+-laser operation.
