Influence of spatial mode structure on the spectrum evolution in tunable lasers

The effect of spatial mode structure on nonlinear processes in the active medium of lasers with elements having an angular dispersion is investigated. It is shown that the 'spatially inhomogeneous broadening' of the spectrum may result in a change in its shape and its broadening. The algorithm for synthesising a continuous spectrum in resonators with a controllable structure of the spectral function is modified.
