A stable Q-switched erbium doped fiber laser emitting at 1558nm is demonstrated using a cadmium selenide (CdSe) material coated onto a side-polished D-shape fiber as the saturable absorber (SA). By elevating the input pump power from the threshold of 91mW to the maximum available power of 136mW, a p...
