Educational Objectives
- Absorption/Emission of Gain Medium
- Optical Pumping
- Fluorescence Lifetime
- Laser Threshold and Slope Efficiency
- Laser Spiking
- Introduction of Losses
- Dynamic Laser Behavior
- Extension: Erbium Doped Fiber Amplifier
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 fluorescence properties are to investigate. With help of a resonator mirror a linear erbium fiber laser is realized. Closing the resonator for a ring the fiber ring laser is built. Both types can be investigated with respect to parameters like the active fiber length, the amount of losses, the pump power, and so on. The ring laser operates bidirectional. An optical diode allows an unidirectional operation. As an extension a fiber coupled 1,55 μm laser diode with controller for EDFA investigations is offered (CA-1241).
