Query: A Review of Cavity Design for Kerr Lens Mode-Locked Solid-State Lasers   We provide a critical review of the fundamental concepts of Kerr lens
mode-locking (KLM), along with a detailed description of the experimental
considerations involved in the realization of a mode-locked oscillator. In
addition, we review recent developments that overcome inherent limitations and
disadvantages in standard KLM lasers. Our review is aimed mainly at readers who
wish to realize/maintain such an oscillator or for those who wish to better
understand this major experimental tool.
