Summary:We present sequentially timed all-optical mapping photography (STAMP) with a slicing mirror in a branched 4 f system for an increased number of frames without sacrificing pixel resolution. The branched 4 f system spectrally separates the laser light path into multiple paths by the slicing mirror placed in the Fourier plane. Fabricated by an ultra-precision end milling process, the slicing mirror has 18 mirror facets of differing mirror angles. We used the boosted STAMP to observe dynamics of laser ablation with two image sensors which captured 18 subsequent frames at a frame rate of 126 billion frames per second, demonstrating this technique’s potential for imaging unexplored ultrafast non-repetitive phenomena.
