Using the reduced graphene oxide(rGO) as a saturable absorber(SA) in an Er-doped fiber(EDF) laser cavity,we obtain the Q-switching operation. The rGO SA is prepared by depositing the GO on fluorine mica(FM) us...
A stable Q-switched erbium doped fiber laser emitting at 1558 nm is demonstrated using a cadmium selenide(CdSe) material coated onto a side-polished D-shape fiber as the saturable absorber(SA). By elevating the in...

We demonstrate a middle infrared ZnGeP_2 optical parametric oscillator pumped by the Q-switched Ho:GdVO_4 laser. When the incident Ho pump power is 4.12 W, the maximum average output power of the ZGP-OPO laser is 2.0...
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 embedd...
