Stability analysis of a non-symmetric femtosecond-cavity-dumped solid-state oscillator

A detailed stability analysis of a Kerr Lens Mode Locked cavity-dumped Ti:Sapphire laser based on a non symmetrical two-folded cavity design is presented. Pulse intensity stability was measured both for the oscillator alone and cavity dumped sources. Stability conditions were compared with a numerical model based on an ABCD matrix Gaussian beam propagation method. The continuous wave and pulsed operation regions were well predicted as was the hard aperture position for mode locking.
