We demonstrate that direct femtosecond laser writing in silver-containing zinc and gallium phosphate glass enables generation of three-dimensional (3D) optical second-order nonlinear microstructures having an χ(2) value about 2.5 times that of quartz. The proposed physical model involves photo-reduction, photo-dissociation, and migration of silver species within the glass matrix. 3D laser-writt...
IN this outstanding 2"x2" Slide Projector, Bausch & Lomb has utilized the experience gained in manufacturing motion picture optical systems to give the user screen images of professional quality from black and white or color slides. Despite the exceptional brilliance of the screen images, slide temperature is kept within safe limits for all normal projection. The Bausch & Lomb 2"x2" Slide Proje...
Laser-driven shock experiments were conducted at a synchrotron facility to investigate the dynamic response of polyurethane foam. These coupled in situ x-ray imaging radiograph foam deformations and determine propagation velocity stress waves. To increase amplitude duration pressure load generated by laser–matter interaction, front surface target was covered with confining layer (water BK7 glas...
*Correspondence: Vladimir S. Shiryaev , G.G. Devyatykh Institute of Chemistry of High-Purity Substances of the Russian Academy of Sciences, 49 Tropinin Street, Nizhny Novgorod 603950, Russia e-mail: [email protected] The recent developments on chalcogenide glass hollow-core microstructured optical fibers (HC-MOFs) are presented. The comparative analysis of simulated optical properties for c...
Fluoride glasses are of great interest for optical applications, as low phonon energy hosts for rare-earth ions. With an increasing need for more compact optical devices that impose higher dopant concentration, research activity has been focused on the fabrication of fluoride glass planar waveguides to produce integrated lasers and optical amplifiers, especially those based on Er3þ-doped glasse...
Chalcogenide glasses from (GeSe2)100-x(Sb2Se3)x system were synthesized, with x varying from 5 to 70, in order to evaluate the influence of antimony selenide addition on nonlinear optical properties and photosensitivity. Nonlinear refractive index and two photon absorption coefficients were measured both at 1064 nm in picosecond regime using the Z-scan technique and at 1.55 μm in femtosecond re...
Some optical surfaces are formed by gravity sagging of molten glass. A glass sheet supported on a ceramic former is heated; the glass becomes a very viscous fluid and sags under its own weight until the lower surface is in full contact with the former. The smooth upper free surface is the required optical surface. Its shape is dependent on the initial geometry and, in optical terms, differs sig...
We report the optical studies of nanohole arrays in metallic coatings on cleaved optical fibers and also on glass substrates. Nanoholes are produced using electron-beam lithography and range in size from 100 to 700 nm; the pitch is varied from 300 to 3000 nm. Transmission properties are examined using visible 632.8 nm and infrared 1550 nm laser light. The observed interference patterns are dete...
