| Abstract: | We derive an analytical expression of the far field distribution of LP 01 mode and calculate numerically.The reswt studied shows that the output beam of the LP 01 mode in the hollow fiber is a dark hollow divergent beam. The dark spot size (DSS) of the beam in the far-field is also given. |
