Abstract

A mode-locked fiber laser was developed by using bis(8-hydroxyquinoline) zinc (${\rm{Zn}}{{\rm{q}}_2}$) as a saturable absorber (SA). ${\rm{Zn}}{{\rm{q}}_2}$ is an organic metal chelate with several advantages such as good saturable absorption, relatively high damage threshold, and an easy, low-cost, and simple fabrication process. The developed SA based on ${\rm{Zn}}{{\rm{q}}_2}$ has a linear absorption (at 1560 nm), modulation depth, and saturation intensity of 1.2 dB, 16.6 %, and ${{95}}\;{\rm{MW}}/{{\rm{cm}}^2}$, respectively. The laser cavity produced a very stable soliton mode-locking operation at 1560.6 nm with pulse duration, repetition rate, and SNR of 1.46 ps, 3.5 MHz, and 60.6 dB, respectively. This work is the first, to the best of our knowledge, to report ${\rm{Zn}}{{\rm{q}}_2}$ as a mode locker.
