Summary: We report a transition metal dichalcogenides-PtSe2 Q-switched single-mode fiber laser operating at 2783.2 nm with a nearly watt-level average output power. By incorporating a PtSe2 coated mirror as a saturable absorber, stable Q-switched laser pulses were obtained with high average power and pulse energy. The operating wavelength range of the PtSe2-coated mirror was also investigated using a plane ruled grating.

Summary: The 20NaF-60P2O5-20Na2O fluorophosphate glass systems doped with 3 wt% of CoO and NiO were investigated for their optical parameters before and after gamma irradiation. The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
