%X Taking the diffraction theory as the foundation,with the maximum output power representing the effect of optical limiter,expression of output power in optical limiter based on nonlinear-refraction was derived.Rules of output power,limiting ability and the best position of medium to limit were analyzed in numerical method when the limiter was irradiated by continuous Gaussian beam.The result indicates that the output power oscillates and weakens along with increasing input power,and its oscillation period depends on the distance between the medium and beam focal point.Limiter′s limiting ability will decrease if waist size of the incident Gaussian beam and the aperture size increase.With a fixed input power scope,medium′s best limiting position will move towards the focal point if waist size of Gaussian beam and the aperture size increase,but the best limiting position will change a lot with different input power scopes.There will be linear and nonlinear scopes when the maximum output power varies along with the transmittance of aperture.
