| Abstract: | The relationship between the launching efficiency and the pumping experimental setup has been studied to investigate the launching efficiency of graded-index channel waveguide. By the ray tracing in the channel waveguide, the dependency of the launching efficiency on the relative position of the pumping beam to the waveguide is analyzed and the coupling conditions are optimized. At last, it is proved that our calculation and analysis are reasonable and correct by the results of the experiments. |
