Q-switched ytterbium-doped fiber laser with zinc oxide based saturable absorber

A Q-switched ytterbium doped fiber laser (YDFL) with a ZnO saturable absorber (SA) is used to demonstrate the generation of pulses in the 1 micron region. The system has a Q-switching threshold of approximately 115.2 mW, and can generate pulses with a 3.0 µs full-width at half maximum as well as a p...
