Longitudinal Structure of the Electromagnetic Field in a Plane-Parallel Resonator
In the preceding chapter we considered a practical optical resonator (i.e., a resonator containing an active medium excited by pumping having a given intensity distribution). The electromagnetic field in such a resonator can be described by a nonlinear wave equation whose solution is a completely defined linear combination of modes (or natural oscillations). The effect of the simultaneous generation of a certain number of transverse modes, which is connected with the linear interaction of these modes, was considered in the preceding chapter. There we assumed that the active medium was uniform in the direction of the optic axis and did not consider the boundary conditions on the end mirrors; thus, we ignored longitudinal modes.
