Abstract
We analyze the high power operation of self-mode-locked solid-state lasers. Excessive Kerr lensing is shown to bring the laser cavity out of the limits of geometrical stability; this situation results in temporal fluctuations, and pulse-break-up into many pulses. Kerr lensing can also reduce the size of the beam to such a point where higher-order transverse modes start to oscillate. Sudden changes in beam size are also examined. Experimental results obtained with a Ti:sapphire laser indicates that two-pulse emission can be more stable than one-pulse emission.
