Simplified cavity design for KLM Ti:sapphire oscillators

A simplified design approach for a hard-aperture Kerr-lens mode-locked Ti:sapphire oscillator was proposed. The technique is based on a simple cavity design and the position of the laser crystal with respect to the cavity mode waist which ensures an enhanced Kerr sensitivity of the oscillator. Experimental results were demonstrated and compared to the numerical calculations. Such a technique can be used and for other laser hosts.
