Using Zinc Oxide (ZnO) nanoparticles embedded in chitin as a saturable absorber (SA), we demonstrate a passive Q-switched erbium-doped fibre laser (EDFL). Following SA fabrication, the SA is integrated in the ring cavity of an EDFL. At an operating wavelength of 1558.8 nm, a stable Q-switching opera...
