Abstract.
This work reports for the first time continuous-wave laser action at room temperature around 1.3 μm in Nd3+ doped LiNbO3:ZnO. Optical spectroscopy has been used to determine the main laser characteristics of 4F3/2?4I13/2 channel, such as emission cross section and excited-state absorption cross section at laser wavelengths. Internal optical losses have been estimated from laser gain experiments. Under non-optimal conditions laser slope efficiencies of 30% have been obtained.
