In the cavity of a self-mode-locked (Kerr-lens mode-locked) laser, a noncircular beam experiences a nonlinear coupling between beam parameters in the x and y planes. This coupling produces a significant change in beam radii throughout the cavity and may result in more than one TEM00 cavity mode. The dramatic nature of this effect is demonstrated with the Ti:sapphire laser as an example.
