Abstract This paper presents the results of our numerical simulation, made by employing Split-step Fourier Method, of pulsewidth dependence on the physical quantities in ring cavity Ti:sapphire laser. It is revealed through the computed results that Kerr-lens effect which is now qiiantitatively considered plays a dominant role in forming ultrashort pulses and its interaction with dispersion finally determines the duration of
the pulse, which sheds light on further theoretical investigation of the mode locking mechanism. Meanwhile, tile self-consistent results also provide a guideline for the experimental alignment of the laser.
