Abstract: The distortion of the distribution of initially pure laser modes caused by the gain saturation is simulated numerically. It is shown that the gain saturation results in a considerable enrichment of the modal spectrum of radiation accompanied by the production and decay of phase dislocations in the far-field domain and at the output of an astigmatic π/2-mode converter.
