Abstract

This work presents fundamentals of the laser-induced micro shock waves (LIMS). The shock wave generation mechanism and the subsequent propagation process of the shock in a micro capillary are investigated. In particular, emphasis is put on well-defined and controllable conditions which also offer the opportunity for potential applications in the future. LIMS are induced by an intense 150 fs laser pulse. In succession, they propagate in the strongly confined 2D geometry of a micro tube. Contactless diagnostic tools are applied to investigate the evolution of density and velocity profiles of the shock waves in the tubes. The initial conditions of LIMS are simulated by the hydrocode MULTI-fs.
