A simple computer model of modelocking using an intracavity nonlinear mirror based on second harmonic generation has been constructed. Saturation of the gain medium is included. The model exhibits experimentally observed features such as a second harmonic conversion efficiency threshold before modelocking occurs. Self Q-switching and modelocking occurs for sufficiently large values of fluorescence lifetime. The model predicts that there is a narrow region above the modelocking threshold which allows steady state modelocking to occur even in long fluorescence lifetime materials.
