Abstract

An investigation is performed of the stability of one-frequency lasing in the one-dimensional model of a traveling-wave laser based on an inhomogeneously broadened active substance relative to a broad class of perturbations which depend on the coordinate and on time. Analytic expressions are derived for the shape of the “contour of the amplification line” for the spectral components of the perturbations of the field for an arbitrary ratio between the width of the luminescence line and the natural width. It is shown that with an increase of this ratio the critical excess of the pumping above the threshold value at which instability develops decreases.
