Mutual Kerr-lens mode-locking is implemented to create synchronized, bidire
ctional pulse-trains in a mode-locked Ti:sapphire laser, in a linear as wel
l as in a ring configuration. A simple ABCD matrix method is used to optimi
ze the location of apertures in the cavity for preferential bidirectional m
ode-locked operation. (C) 1999 Elsevier Science B.V. All rights reserved.
