Mutual Kerr-lens mode-locking is implemented to create synchronized, bidirectional pulse-trains in a mode-locked Ti:sapphire laser, in a linear as well as in a ring configuration. The latter can be either due to the pump/laser mode overlap (soft aperture) or a physical (hard) aperture. This effect is called self-focusing and has important implications for passive mode locking of lasers ( Kerr lens mode locking) and for optical damage of media ( catastrophic self-focusing ). Kerr-lens mode-locked (KLM) bulk lasers are very attractive for the generation of ultrashort pulses for numerous applica-tions in frequency conversion [15], nonlinear microscopy [69], and ultrafast spectroscopy [10, 11]. Such combined mechanism has the same effect as a saturable absorber.

Design issues for this Transient autocorrelation traces and spectra The general principle behind Kerr-Lens Mode Locking is sketched in Fig. 7.1. A pulse that builds up in a laser cavity containing a gain medium and a Kerr medium experiences not only self-phase modulation but also self focussing, that is nonlinear lensing of the laser beam, due to the nonlinear refractive in- dex of the Kerr medium.

A new method mutual Kerr-lens mode-locking is presented which provides for a means to define the crossing point of counter-propagating waves in a ring or linear laser, without the use of an saturable absorber. The ring cavity generates ultrashort pulse trains by means of soft-aperture Kerr-lens mode locking in either the uni-directional or the bi-directional lasing mode.
