Self-starting of a self-mode-locked Ti:sapphire laser has been demonstrated, without any additional elements other than those necessary for self-mode locking. This self-starting is attributed to a gain saturation lens, as with self-mode locking to a Kerr lens. I achieve the self-starting by optimizing and cascading the cavity loss modulation induced by the gain saturation lens and the Kerr lens. Stable pulses shorter than 100 fs in duration are obtained at a wavelength near 840 nm.
