All-fiber graphene passively q-switched nanosecond thulium doped fiber laser at 1900 nm

All-fiber graphene passively q-switched nanosecond thulium doped fiber laser at 1900 nm

We successfully demonstrated a simple, compact and low cost passive Q-switched Thulium doped fiber laser (TDFL) at long wavelength of 1854.3 nm regions in conjunction with 1552 nm pump excitation. A stable pulse has been generated using graphene film based saturable absorber (SA). The graphene...
