“…This result was in a good agreement with several experimental observations [16,17]. However, the influence of the concentration of inhomogeneities on the evolution of nanogratings, to our knowledge, has not been investigated previously, leaving unexplained the results of several experiments [15,[59][60][61].…”

“…Additionally, impurities that were embedded in bulk fused silica also contributed to nanograting formation. They also enhanced and improved the nanoplasma incubation process [15,[59][60][61]. In previous studies, the dynamics of laser interaction with inhomogeneities of different nature was studied for voids [48], for nanospheres of densified fused silica [41], and for metallic nanoparticles [62].…”

“…15 Furthermore, doping of pure silica glass with Ge, F, and P was demonstrated to affect the threshold for nanograting formation. 16 Recently, evidence for femtosecond laser-induced nanogratings has been observed in glasses other than SiO 2 , including several studies reported nanogratings in GeO 2 glass, [17][18][19] binary titanium silicate glass (ULE, Corning), 20,21 and two multicomponent borosilicate glasses (BK7 and Borofloat 33, Schott). 20,22 Germanium dioxide is formed by a three-dimensional network of [GeO 4 ] tetrahedra with all bridging oxygen atoms, whereas ULE glass also possesses structure similar to pure SiO 2 24 were not revealed using scanning electron microscopy despite the induced retardance was of the same level as in Borofloat 33.…”

“…The performance of the waveguides fabricated by ultrafast laser inscription depends on the ultrafast laser pulse (wavelength, pulse energy, pulse duration, repetition rate, and polarization) and on processing conditions (scan speed, focal depth, and irradiation geometry), as well as on the material response (substrate material properties) [3]. This technique has been successfully applied to fabricating channel waveguide devices in a wide variety of transparent materials, including glasses, crystals, ceramics, and polymers [4][5][6][7][8][9][10][11][12][13].…”
