Abstract
Two-color side-view probing of light-matter interaction in the focal volume of a tightly focused fs-laser pump pulse reveals charge dynamics with 0.9 μm lateral resolution and ~45 fs temporal resolution. Use of two colors is advantageous for probing optically excited plasma regions with different density. Holographic digital focusing was were implemented to minimize the deviation of the focusing plane caused by chromatic aberrations.
