“…Another phenomenological relation has been previously observed in titania-silica mixtures. 5 The authors concluded that internal threshold fluency of standing wave follows the observed a power law dependence on pulse duration and linear dependence on the absorption band-gap expressed in eV. This phenomenological formula has been previously reported also on pure metal oxide coatings by Mero et al: 42…”

In this study, we report on our recent progress in research of single layer mixed zirconia-silica and niobia-silica composite coatings prepared by Ion Beam Sputtering technique. All coatings of the same optical thickness were characterized in terms of reflection/transmission spectrometry, X-ray diffraction, atomic force and optical microscopy, optical back-scattering and optical resistance (laser-induced damage threshold -LIDT) in subpicosecond mode. The optical resistance, TIS and LIDT results reveal clear dependence on high refractive index material content in composite coating and its crystalline structure. The results are interpreted and discussed by the means of different models available in literature.

“…For example, it can be used to tune the refractive index in combination with laser irradiation stability of phase shift in optical nanocomposites [65,66]. By employing plasmonic metals in dielectric or semiconducting matrices, the approach can be used to influence the lateral plasmon enhanced electric field for sensing [67] or photocatalytic [68] applications.…”

Compositionally modulated ripples during composite film growth: Three-dimensional pattern formation at the nanoscale

Three-dimensional, ion-induced nanoscale pattern formation in the growth mode is studied for a bicomponent thin film. C:Ni films were grown by dual ion beam cosputtering applying an assisting oblique-incidence lowenergy Ar + ion beam. Their microstructure was determined by scanning electron, atomic force, and transmission electron microscopy, as well as by grazing-incidence small-angle x-ray scattering. The role of ion-induced collisional effects was investigated by binary collision computer simulations. The formation of compositionally modulated ripples on the C:Ni film surface is demonstrated. They consist of metal-enriched topographic crests and carbon-enriched valleys. Since the surface is constantly covered by incoming species, this pattern is transferred into the bulk as a periodic array of Ni 3 C nanoparticles or of Ni-enriched regions in a carbon matrix. Lateral ripple propagation is shown to be one of the crucial phenomena for the film morphology. The essential experimental features are reproduced by the computer simulations. The results reveal the importance of ion-induced preferential displacements as the driving factor for a surface instability, which gives rise to the observed pattern formation.

In the ultra short laser pulse regime, the damage process is driven by the interaction of the laser pulse with the electronic structure of the material. The way of excitations in dielectric materials is dominated by multi photon and avalanche ionization processes. Often, the complete theoretical description is limited by the lack of knowledge of the precise material properties. Usually, LIDT measurement data are only available for pure materials (e.g. TiO 2 , Ta 2 O 5 or SiO 2 ). The development of composite materials opens the way to vary material properties, continuously. Additionally, all material changes are based on the same chemical elements in different compositions. The paper compares measurement results of the University of New Mexico and Vilnius University performed on the same set of Ti x Si 1-x O 2 -mixtures to calculations based on Keldysh theory. When applying simple approximations for the physical properties of the mixture, the theoretical description agrees well with the measurement results.
