It shows clear WebJul 29, 2024 · Over the last decade, the use of chirped fibre Bragg gratings (CFBGs) in detonation velocity experiments has been steadily increasing. In this paper, we show how CFBG design parameters—chirp-rate, reflectivity and apodisation—affect linearity in detonation velocity tests. It is found that the optimal CFBG detonation velocity …
WebJul 1, 2024 · Firstly, we manufacture a CFBG with above chirped phase mask. Secondly, we replace the chirped phase mask by a common phase mask (length: 27 mm, period: 1073.7 nm) and use C + L ASE (1528−1602 nm) instead of 1060 nm ASE. At last, keep the fiber locked in the same position and launch the excimer laser again.
