A numerical investigation is reported of a distributed model of a wide-aperture laser with frequency detuning. When the detuning is negative, successive changes in the optical field structures occur on increase in the detuning: a near-homogeneous optical field is followed by regular small- and large-amplitude self-waves in the optical field profile, and these are succeeded by structures irregular in space and time. The range of parameters of the laser-active medium, in which quasi-sinusoidal periodic structures can be observed, is found. A comparison is made of the characteristics of these waves with the values obtained on the basis of a bifurcation analysis of this laser system. Similar periodic self-wave profiles of the optical field do not appear when the frequency detuning is positive. (laser fields and cavities)
