“…Лазер состоит из одного АЭ 1, глухого зеркала 2, шести поворотных зеркал 3−9 и ПЛЗ 10. Для стабилизации частоты и сужения спектра генерации была использована пропускающая объемная брэгговская решетка 11, записанная в фототерморефрактивном стекле [12], синтезированном в университете ИТМО. За счет чисто фазового характера записывае-мых решеток данный материал предоставляет возможность получения решеток с дифракционной эффективностью до 99%.…”

Предложен способ стабилизации частоты и сужения ширины полосы генерации импульсного твердотельного Nd-YAG-лазера с динамическим самоадаптивным многопетлевым резонатором путем введения внутрирезонаторной стационарной объемной брэгговской решетки. Это позволяет зафиксировать частоту и уменьшить ширину спектральной линии генерации с 18 до 4 pm. DOI: 10.21883/PJTF.2017.08.44539.16571

“…By now, the photothermoinduced crystallization and properties of the PTR glass are investigated well enough. For example, the fluoride PTR glass was designed and synthesized in ITMO University, Russia [13]. It is a photosensitive multicomponent sodium-zinc-alumina-silicate glass containing fluorine (6 mol.%) and a small amount of bromine (0.5 mol.%).…”

Today, silicate photothermorefractive (PTR) glasses are well known as a holographic medium for fabrication of holographic volume diffractive optical elements. The photothermoinduced crystallization process is used for recording high-efficiency phase volume holograms in this material. These holograms are used for developing unique diffractive optical elements that provide new opportunities for the laser technique, for example, narrowband filters for solid-state lasers and laser diodes, beam combiners, holographic collimator sights, chirped gratings for laser pulse compression, etc. By now, the photothermoinduced crystallization and properties of the PTR glass are investigated well enough. However, there are some issues and features still, which are solved in the present work. The mechanism of refractive index change in fluoride photothermorefractive glass during photothermoinduced crystallization and refractive index profile of the volume Bragg gratings were discussed. We studied a fine structure of a core-shell system inside fluoride PTR glass in which a silver nanoparticle presents the core and crystalline phases of silver bromide and sodium fluoride present the shell. We report on the optical properties of volume Bragg gratings in chloride PTR glass after femtosecond laser bleaching. We demonstrated that the bleaching procedure significantly reduces the absorption and increases the thermal stability of the Bragg gratings.

“…At present, PTR glasses can be classified as polyfunctional materials combining, in themselves, the properties of several monofunctional materials such as the photosensitive, photorefractive, laser, luminescent, and plasmonic ones [5]- [7]. In particular, the possibility of recording high-efficiency phase volume holograms such as Bragg gratings was shown in [8]- [11]. Today, Bragg gratings based on PTR glasses are used as laser line narrowing and stabilizing filters, spectral and spatial filters, Raman filters, compressors for fs and ps-lasers, spectral beam combiners, high power beam splitters, etc.…”

Photo-thermo-refractive (PTR) glasses are the class of polyfunctional materials that combine the properties of several monofunctional materials such as photo-refractive, laser, luminescent, and plasmonic ones. Based on PTR glasses, various diffractive holographic elements and photonic devices were developed in both the volume and fiber versions. In this paper, the fabrication of optical planar waveguides on PTR glass by low-temperature ion exchange is reported for the first time. Planar waveguides were fabricated through substituting the sodium ions in glass by silver, potassium, rubidium, and cesium ones from the nitrate melts. The silver waveguides were shown to have the largest depth (27 μm) and reveal no birefringence. For the silver waveguides, an increase in the refractive index is caused by differences in the polarizabilities of cations exchanged. The maximum increment of the refractive index was observed in the cesium waveguides (0.0512). An increase in the refractive index and also appearing the birefringence in potassium, rubidium, and cesium waveguides are found to be due to the compressive mechanical stresses and their relaxation. The potentialities of the ion exchange technology for fabricating, in PTR glasses, planar gradient waveguides with low losses (0.5 dB/cm) are demonstrated, the potentialities extending the application field of PTR glasses in photonics.Index Terms-Ion exchange, optical waveguides, photo-thermorefractive glass. 0733-8724
