Abstract: Terawatt laser pulses obtained after temporal compression due to nonlinear spectrum broadening in thin glass plates with subsequent dispersion compensation by chirped mirrors are experimentally characterized by spatially encoded spectral phase interferometry. The proposed method allowed to reconstruct the spectral and temporal phase of obtained 16 fs laser pulses with up to 20 mJ of energy in a single-shot mode with spatial resolution.

Keywords: ultrashort femtosecond pulses, spectrum broadening in transparent dielectrics, spatially encoded spectral phase interferometry.
