“…Therefore, the band with central wavelength at 360 nm was associated with hole centers. In order to understand the origin of the band centered at longer wavelengths, we melted glass without bromine [19]. Then, samples were ground and polished and were UV-exposed and thermally developed.…”

“…Absorption spectra were measured, and then silver containing particles absorption was extracted and decomposed with Gaussian functions. It was shown that this decomposition can be performed with only two bands: one centered at 370 nm and one centered at 410 nm, and none of the bands having central wavelength above 410 nm was required [17,19]. Also, no band in the visible range appeared if no silver is added.…”

This chapter presents a survey oλ recent achievements oλ the ITMO University (St. Petersburμ, Russia) in developinμ new holoμraphic media such as luoride, chloride, and bromide silicate photo-thermo-reλractive (PTR) μlasses as well as the holoμraphic difractive optical elements that are the volume "raμμ μratinμs recorded in the μlasses λor improvinμ dramatically the parameters oλ laser systems oλ diferent types. The photo-thermo-induced crystallization process and the properties oλ luoride, chloride, and bromide PTR μlasses are demonstrated. This new technoloμy enabled recordinμ hiμh-eiciency phase volume holoμrams in the optical quality silicate μlass. These holoμrams are used λor developinμ a number oλ unique difractive optical elements that provide new opportunities λor the laser technique. Some examples oλ desiμninμ and λabricatinμ oλ holoμraphic optical elements such as the super-narrowband ilters λor solid-state lasers and laser diodes, laser beam combiners, and collimator siμhts are demonstrated in this chapter. It is shown that the PTR μlass doped with rare earth ions can be used λor desiμninμ lasers with "raμμ relectors and distributed λeedback.

“…It is well known that the sodium fluorine is hardly solvable in silicate glass; it is evaporating from the glass surface even at the comparatively low temperatures. In [34,35] was shown that in the photothermo-refractive glasses no photoinduced deposition of NaF takes place in the absence of KBr in the glass composition. In [35] in such glass was observed the absorption band of colloid silver, covered by the layer of AgBr.…”

Intr"ducti"nNano-size particles of noble metals (Ag, Au, Pt) are today a subject of thorough attention of scientific researchers and of technologists, because these particles reveal the wide range of physical features, absent in the case of bulk media. Size-controlled optical properties of Ag-nanoparticles open good prospects for potential technological applications -such as diffraction elements, optical filters, nanoplasmonic devices, bi-sensors, and nonlinear media. Silver nanoparticles can be produced in various media -in water solutions, in polymers, in glasses, and in crystalline media. For instance, the long period in photographic imaging technique was based on the photoinduced production of Ag nanoclusters in the crystals of AgHal (the latent image). At the same time one can say that the inorganic glasses are the unique matrix for silver nanoparticles formation. The wide temperature range of glass viscosity growth provides the possibility to control over the Ag nanoparticles size within the wide range by means of modifying the temperature and duration of thermal processing. In the fact, only such kind of matrix makes it possible to control and investigate all the stages of Ag nanoparticles formation, including the starting stage. Glass coloring by introduction of the metallic Ag nanoclusters is one of the ancient methods, known by humanity [1]. The mechanisms, leading to nucleation and growth of such nanoclusters, are the scientific and technology problem, important both for colored glass production and for all other potential applications of glass with silver nanoparticles [2][3][4][5]. The researches on silver nanoclusters formation comprise numerous technical approaches. Especially interesting are the methods, based on the use of ionizing radiation, are especially interesting due to their ability provide either local irradiation or to irradiate the whole volume of the glass. In this case it is comparatively simple to provide the control over concentration and average size of metallic nanoclusters. For instance, the controlled photon irradiation is used for production of photosensitive [6], polychrome [м] and photo-thermorefractive [н] glasses. Very often all these types of glasses are called the photosensitive one (PS). Further within this chapter we shall use this word. 10www.intechopen.com
