Abstract :
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 ω0. 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
