| Resumo: | We report the demonstration of high-average-power passively [Formula Omitted]-switched laser oscillation from [Formula Omitted] ions in zinc selenide. A semiconductor saturable absorber mirror was used as a passive [Formula Omitted]-switch element. Using a 60% R outcoupler, the pump-limited output power was 515 mW. The spectral center of the laser was 4045 nm. The pulse repetition frequency (PRF) at maximum power was [Formula Omitted] with a corresponding minimum pulsewidth of 64 ns Full-Width Half-Maximum. The pulse energy and peak power were [Formula Omitted] and 8.3 W, respectively. The average output power was limited only by available pump power and increased with a slope efficiency of 22%. No thermal rolloff of slope-efficiency was observed. The beam quality was measured to be [Formula Omitted]. The temporal stability of the pulsed output was characterized. Thermal effects were shown to play a significant role in determining the PRF of the output. |
