Based on the traditional ABCD law, the relative variation of spot size in the laser medium is analyzed. The results show that the introduction of SESAM destroyed the continuity of the laser stability and enhanced the nonlinearity of the laser. So the mode-locked pulses are generated easily due to the SESAM. The spectrum width of 40пш has been obtained experimentally.
