The beam mode and the output characteristics of a 2kw CW CO laser with tunable mode resonator (TMR), in which the beam mode can be tuned continously from TEM°, mode higher-order mode has been described. At the premise of no exchanging the structure of the resonator, in order to fit the beam quality for different targets of laser processing, it is the expectant goal to the people for long time to make the Laser can continuously select any output beam mode which it can be changed from TEMoi mode to higher-order mode. We ingeniously use the change of the relative location between the ray axis and the symmetrical centre of the active medium in this paper, it makes one set of resonator output several beam modes become in truth.
