A detailed study of cavity stability is conducted using an optimized waist Gauss-Laguerre representation of cavity modes. The parametric scaling of modal properties on cavity geometry including gain overlap, scattering and wing-clipping losses, in addition to diffraction, is obtained via an expansion of the round-trip matrix in G-L modes and subsequent diagonalization. Modal waist in laterally open cavities follows from the optimization for the round trip coefficient relative to /spl omega//sub 0/. Numerical values for the round trip modal losses are obtained through a fast numerical solution of the mathematical model equations, using the numerical algorithm PREVEU.
