摘要

Transition metal oxides (TMOs) have been successfully demonstrated as Qswitchers for pulsed fiber lasers. In this work, the ferroferric-oxide (Fe ₃ O ₄ ) nanoparticles are synthesized via chemical co-precipitation. Filmy Fe ₃ O ₄ /polyvinyl alcohol (PVA) is adopted as a Q-switcher in the 1 μm region. The Fe ₃ O ₄ /PVA film has the modulation depth of 7.8% and saturable intensity of 71.32 MW/cm ² , respectively. By incorporating the Fe ₃ O ₄ /PVA film into Yb-doped fiber laser (YDF) cavity as a saturable absorber (SA), the stable Q-switching operation is obtained in 77-157 mW pump power range. At the pump power of 147 mW, the Q-switched YDF laser emits stable laser pulses with the maximum single pulse energy of 50.35 nJ and shortest pulse duration of 1.63 μs. The experimental results indicate that the zero-dimensional Fe ₃ O ₄ nanoparticles have a bright prospect for nonlinear optics applications.
