In this study, we investigated the variation of the femtosecond pulse duration of the threshold fluence of fused silica by a single-shot irradiation at a wavelength of 400 nm. The single-shot threshold fluence was obtained from the relationship between the crater area based on the crater shape and the irradiation fluence. The crater shape was divided into two affected regimes depending on the pulse duration and the laser fluence. The crater depth and each threshold fluence for the corresponding two affected regimes were also measured. We have found that shorter pulse duration provides more energy-efficient results.
