Abstract :
A new method for measuring the self-focusing parameters of transparent materials is reported. The technique consists of using lenses with different focal lengths to induce intrinsic bulk damage at low powers where catastrophic self-focusing is absent and then comparing the results to analytical calculations. Using this technique, the self-focusing parameters for sapphire are determined.
