Single-shot Ultrafast 2D-burst Imaging by STAMP utilizing Spectral Filtering (SF-STAMP)

Single-shot 25-frame burst imaging of ultrafast phase transition of Ge2Sb2Te5 with a sub-picosecond resolution

“…To increase the number of STAMP frames by a simpler method, we introduced a scheme utilizing a "spatially and temporally resolved intensity and phase evaluation device: full information from a single hologram (STRIPED FISH)" [15][16][17] method to STAMP and successfully demonstrated five-frame burst imaging by STAMP utilizing spectral filtering (SF-STAMP). 18,19) In the present study, we captured ultrafast 2D-burst images of the crystalline-to-amorphous phase transition of Ge 2 Sb 2 Te 5 (GST) with sub-picosecond temporal resolution on a singleshot basis for the first time, by improving the SF-STAMP setup to acquire 25 frames in a single-shot measurement. GST can undergo repeated phase changes between its crystalline and amorphous phases.…”

Sequentially Timed All-Optical Mapping Photography for Real- Time Monitoring of Laser Ablation: Breakdown and Filamentation in Picosecond and Femtosecond Regimes

“…For observing a detailed process in filamentation induced by intense femtosecond laser, the number of frame was also increased. Here, we present movies of plasma filament generated inside a glass acquired by an improved STAMP system, called SF-STAMP (STAMP utilizing spectral filtering) [20][21][22]. Figure 15 shows the schematic of experimental setup.…”
