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. It is important to study the early startup stage of mode locking: which is the key to the understanding of physical mechanisms for pulse formation in the laser. The mode-locking technique preferably used is Kerr-lens mode-locking [11]. Q-switching instability restricts pulse shortening in Kerr-lens mode-locked lasers (KLMLs).However, Q-switching suppression in KLMLs has not been discussed to date because of the difficulty of treating the Kerr-lens effect theoretically.We investigated parameter ranges for stable Kerr-lens mode locking (KLM) against Q switching theoretically and experimentally. KLM means Kerr-lens mode-locking. The mode-locked spectrum (FWHM) exceeds the A simple ABCD matrix method is used to optimize the location of apertures in the cavity for preferential bidirectional mode-locked operation. Transient autocorrelation traces and spectra Brabec T, Spielmann C, Curley PF, Krausz F. Optics Letters, 01 Sep 1992, 17(18): 1292-1294 DOI: 10.1364/ol.17.001292 PMID: 19798161 . 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 ). Initiation of Kerr-lens modelocking depends on the strength of the nonlinear effect involved. If the laser field builds up in a cavity the laser has to overcome the region of continuous-wave operation, which often is favoured by the pumping mechanism.

Self-focusing in conjunction with an intracavity aperture creates a power-dependent amplitude modulation in laser oscillators, which allows passive mode locking. Search: Matlab Nonlinear Optics.

KERR-LENS AND ADDITIVE PULSE MODE LOCKING soft aperture hard aperture gain The U.S. Department of Energy's Office of Scientific and Technical Information Search: Matlab Nonlinear Optics. The latter can be either due to the pump/laser mode overlap (soft aperture) or a physical (hard) aperture. Nonlinear effects in optical fibers originate from the intensity dependence of the refractive index and stimulated inelastic scattering As the bit rate of the transmission system gets higher and higher 40 Gb/s to 100 Gb/s the modeling of proposed modulation techniques is very important so as to avoid costly practical demonstration 1 Examples
