Abstract

A novel approach for interferometric analysis of ultrafast transient processes as short as 10⁻¹³–10⁻¹⁴ sec is suggested. The method of holographic storage of ultrafast time–space images in spectrally selective hole-burning materials is used. It is shown that differential interferometric comparison of time–space images, which are permanently stored, provides an effective means to resolve ultrafast transient signals in space and in the spectral domain.
