| Abstract: | In this paper,we have studied experimentally the properties of the mode structure and modes evolution of a slab waveguide CO2 laser with a far field intensity distribution of a single spatially sup-pressed peak. It has been found that the laser mode is a new single mode of a slab waveguide CO2 laser,which has a different mode structure from the known mode of slab waveguide gas laser. |
