Investigation of passively Q-switched and mode-locked operation using Cu nanoparticles doped Indium Selenide as saturable absorber at 1.5-mu m region

A reliable Q-switched and mode-locked operation at the 1.5-mu m region has been demonstrated using copper nanoparticles (Cu NPs)-doped Indium Selenide (In2Se3). The Cu NPs were produced using pulsed laser ablation (PLA) in a PVA solution before mixed it with In2Se3 solution. Then, the Cu/In2Se3 solu...
