This fiber laser setup offers a multitude of experimental performances.Laser threshold and slope efficiency of the 980 nm pump laser can be examined.Coupling the pump light in the erbium fibers, absorption and fluorescenceproperties are to investigate. With help of a resonator mirror a linear erbiumfiber laser is realized. Closing the resonator for a ring the fiber ring laseris built. Both types can be investigated with respect to parameters like theactive fiber length, the amount of losses, the pump power, and so on. The ringlaser operates bidirectional. An optical diode allows an unidirectional operation.As an extension a fiber coupled 1,55 μm laser diode with controller for EDFAinvestigations is offered (CA-1241).
