The original question is about the spacial mode of a laser, not how the
shape deforms in fiber or any media when the light propagates, not to
mention frequency domain, which is almost completely irrelavant.
For a confocal resonator, the spacial mode can be analytically solved to
be Hermite-Gauss functions, in which the TEM00 mode corresponds to a simple
2D Gaussian beam.
So for edge-emitting LD, the spacial mode should be 2D Gaussian beam, although
not degenerated since the ratio of the dimentio
