Passively Q-switched erbium-doped fiber laser with mechanical exfoliation of 8-HQCDCL(2)H2O as saturable absorber

In this work, we have experimentally reported passively Q-switched erbium-doped fiber laser (EDFL) by incorporating 8-Hydroxyquonolino cadmium chloride hydrate (8-HQCDCL2H2O) as saturable absorber (SA). The 8-HQCDCL2H2O SA was prepared by mechanical exfoliation using the scotch tape. The SA was then...
