We analyze the mode properties of a laser with a Gaussian gain profile by using the beam propagation method. The resonance properties of the Petermann K factor and the M2 beam quality are shown to be related in the vicinity of degenerate cavity geometries. K is unity for a confocal cavity, even under conditions with strong gain guiding, while M2 is a maximum.

  16. The standard result for phase, (D-A)/2B, results in a flat phase for A=D (i.e., all symmetric resonators) as opposed to Eq. 6 that is consistent with our numerical result for variation of Petermann’s K factor.
