We present a new approach for the calculation of resonator mirror shapes based on a simulated annealing optimization algorithm. Compared with the possibilities of conventional resonators with spherical mirrors, the method presented permits a large mode volume of the stationary field distribution of the oscillating lowest-loss mode and an increase in its loss discrimination against the remaining ensemble of other modes at the same time. We present results for circular symmetric graded-phase mirrors that yield a difference of 30% between the diffraction losses of the fundamental mode and of other evaluated higher modes.
