Self-channeling of femtosecond laser radiation in transparent two-component condensed medium

摘要

We have observed self-guiding of a single femtosecond visible laser pulse in the bulk of transparent nonlinear media (SiO_2, KDP) and in the water. The dependence of filament length on laser pulse energy was measured. Continuous open-ended channels and frozen modifications of the matter were observed in transparent two-component condensed medium (thin glass plate placed in water).
