Paper Abstract

Digital holography (DH) technique allows obtaining quantitative amplitude- and phase-contrast images. However, there are only several attempts to use advantages of digital holography in time resolved manner. Herewith we demonstrate that combination of conventional off-axis DH and ultrashort probing laser pulses results in versatile tool suitable for ultra-fast phenomena studies. We demonstrate its applications in spatial-temporal characterization of ionizing pre-damage propagation of femtosecond pulses in transparent material as well as characterization of post-damage ablation processes in metals. Phase-and amplitude-contrast images are obtained in single-shot mode with the best to our knowledge temporal resolution of ≈ 30 fs.
