| Abstract: | There are many definitions about efficiency in the textbook of principle of lasers , which are subjected to confuse each other. After detailed analysis, the pumping quantum efficiency, the fluorescence quantum efficiency and the slope efficiency are distinguished clearly. The special case of the quantum efficiency being higher than 100% is also studied in thulium-doped fiber lasers. These are helpful to students＇comprehension. |
