  • We demonstrate the generation of a Q-switching pulse train in an erbium-doped fiber laser (EDFL) cavity using a newly developed cadmium selenide (CdSe) based saturable absorber (SA).The SA is obtained by embedding CdSe nanomaterials into a polymethyl methacrylate (PMMA) microfiber.It is incorporated into an EDFL cavity to generate a Q-switched laser operating at 1533.6nm.The repetition rates of the produced pulse train are tunable within 37-64kHz as the pump power is varied from 34mW to 74mW.The corresponding pulse width reduces from 7.96μs to 4.84μs,and the maximum pulse energy of 1.16nJ is obtained at the pump power of 74mW.

Abstract: We demonstrate the generation of a Q-switching pulse train in an erbium-doped fiber laser (EDFL) cavity using a newly developed cadmium selenide (CdSe) based saturable absorber (SA).The SA is obtained by embedding CdSe nanomaterials into a polymethyl methacrylate (PMMA) microfiber.It is incorporated into an EDFL cavity to generate a Q-switched laser operating at 1533.6nm.The repetition rates of the produced pulse train are tunable within 37-64kHz as the pump power is varied from 34mW to 74mW.The corresponding pulse width reduces from 7.96μs to 4.84μs,and the maximum pulse energy of 1.16nJ is obtained at the pump power of 74mW.
