ANALYTICAL DESIGN OF SYMMETRICAL KERR-LENS MODE-LOCKING LASER CAVITIES

Analytical expressions for the spot size and the Kerr-lens mode-lockin g (KLM) strength can be represented as explicit functions of the Posit ion in the cavity, the laser power, and the stability parameter for a four-mirror figure-Z laser resonator. The results indicate that the KL M strength achieves its maximum value at the edge of the stability ran ge. Self-amplitude modulation and group-velocity dispersion compensati on can be established by a prism pair. Simultaneously obtaining a larg e pumping efficiency and KLM is possible for this cavity.
