Standing wave field distributions in three classic types of graded-index antireflection coatings are studied. These graded-index antireflection coatings are designed at wavelengths from 200 nm to 1200 nm, which is the working wavelength range of high energy laser system for inertial-fusion research. The standing wave field distributions in these coatings are obtained by the numerical calculatio...
In this work, an anti-reflection coating was prepared in the region (400-1000) nm of wavelength, with a double layer silicon dioxide (SiO2) as inner and second mixture titanium (TiO2) certain ratios, outer using chemical spraying method number 6 sprays SiO2 12 - TiO2. Using deposited on glass substrate different SiO2, fixed TiO2-SiO2. The optical structural properties were determined UV-Vis spe...
Thermodynamical fluctuations impose random noise on the position of optical components. It is predicted that this thermal noise will limit the sensitivity of interferometric gravitational-wave detectors in their most sensitive frequency band. Thermal noise originating from optical coatings was first considered in the context of interferometric gravitational wave detectors. Its true significance...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
We report the first results of self-assembled nanostructures using colloids for antireflection optical coatings. Two-dimensional (2D) periodic nano-structures were made by using self-assembled 2D colloidal crystals on top of a transparent substrate. An atomic force microscope was used to evaluate the quality of the nanostructure. The feature size of the structures was around 105 nm. This sub-wa...
The reflection of light at interfaces limits the performance of optical components. An anti-reflection (AR) coating layer is often applied to improve the optical transmittance. Besides the commonly used singleor multi-layer coatings reducing the reflection, subwavelength nanostructures have gained more attention as an effective AR feature. A wide choice of materials can be nanostructured withou...
