英文摘要	recently, femtosecond laser direct writing in porous glass is emerging as a powerful technique for building arbitrary 3d hollow micro/nanostructures in bulk glass materials. in this study, we investigate the pulse duration dependence of laser intensity window for inducing a single nanocrack inside porous glass by femtosecond laser direct writing. we find that the window for a single nanocrack increases with the pulse duration, while the roughness of side walls in the nanocracks becomes higher for pulses longer than similar to 300 fs. when the femtosecond laser pulses of an optimized duration of similar to 200 fs are chosen, a sufficiently broad range of laser intensity (similar to 44 % of the structuring threshold) for creating a single nanocrack can be obtained, while smooth sidewalls required by nanofluidic applications can still be maintained. the reported results will be beneficial not only for the development of the 3d femtosecond laser micro/nanostructuring techniques, but also for gaining a deeper understanding of the physical mechanism behind the nanograting formation induced by femtosecond laser irradiation in glass and other transparent materials.
