Effect of the Position Variation of the Launcher Cut on the Conversion Efficiency of the Gaussian Beam in a Denisov-type Mode Converter

In this abstract, the position variation of the launcher cut was slightly adjusted for decreasing the effect of the diffraction on the launcher conversion efficiency of the Gaussian beam from the T$E_{28,8}$ mode in Denisov converter, which shows that the Gaussian beam content can be improved indeed
