Laser-induced densification of fused silica using spatially overlapping sub-30fs pulses

Yves Bellouard, Farhang Nabiei, Ya Cheng

Over the past several years, non-ablative femtosecond laser exposure with spatially overlapping (i.e., spatially cumulative) pulses has emerged as a key process in three-dimensional writing of patterns in bulk of dielectric substrates. When temporally non- ...

Stress-state manipulation in fused silica via femtosecond laser irradiation

Philippe Gillet, Yves Bellouard, Charles Michel Henri Pépin, Ya Cheng

Controlling the stress in glass after laser exposure is of prime importance not only for photonics applications, but also for preserving the mechanical integrity of glass components in general. The sub-surface exposure of fused silica to femtosecond laser ...

Formation of nanogratings in a porous glass immersed in water by femtosecond laser irradiation

Yves Bellouard, Min Huang, Ya Cheng

Irradiation of intense ultrafast laser pulses in glasses can lead to formation of nanogratings whose periods are significantly smaller than the incident irradiation wavelength. The mechanism of the exotic phenomenon is still under hot debate. Here, we acce ...
