Abstract
A self-made saturable absorber (SA) based on hybridized graphene oxide (GO) and ${{\rm Fe}_{3}}{{\rm O}_{4}}$ nanoparticles (FONP) was inserted into a linear cavity to generate a passively $ Q $-switched solid-state ${\rm Nd}\text:{{\rm YVO}_4}$ laser operating at the 1.3 µm waveband. The laser had a minimum pulse width of 163 ns and a maximum repetition rate of 314 kHz. This experiment, to the best of our knowledge, is the first to demonstrate that hybridized GO and FONP (GO-FONP) can be used as an SA in passively $ Q $-switched pulse lasers. Results show that GO-FONP has the potential to be used for passively $ Q $-switched laser generation.
