“…The intrinsic loss defines the theoretical attenuation of a glass which excludes extrinsic loss factors such as crystals and inclusions, transition metals, O-H, water, and other impurities, glass inhomogeneity, air bubble, etc [27][28][29]. The analysis method for determining the total intrinsic loss has been discussed in reference [30].…”

“…It is also known that by tapering down a fibre with sub-wavelength features can also improve FEWS sensing since large proportion of light cannot be confined in to the fibre core which propagates along the fibre surface [18,19]. However, unlike silica, which can be easily tapered down to nano-scale, most chalcogenide glass fibres are difficult for post-processing due to thermal instability and poor mechanical strength [19,[27][28][29]. There are two main advantages for using a multimode Ge-Te-Se fibre in this investigation.…”

“…There are a few of mid-IR transmitting optical fibers, including chalcogenide, germanium oxide, sapphire, zirconium fluoride, and hollow waveguides [35][36][37][38][39]. To be employed as an endoscopic delivery system, the fiber needs to be biocompa- tible, flexible, and robust to tolerate the strong laser-tissue interaction at the fiber tip.…”

Urinary calculus fragmentation during Ho: YAG and Er:YAG lithotripsy

Background and Objectives: We tested Ho:YAG and Er:YAG laser ablation of human urinary calculi to determine if Er:YAG is a more efficient lithotripsy device. Study Design/Materials and Methods: Ablation efficiency of Ho:YAG and Er:YAG lasers was tested at varying energy settings, ranging from the damage threshold to clinical energy setting associated with Ho:YAG laser. Stones of known composition (calcium oxalate monohydrate (COM), cystine, and uric acid (UA)) were irradiated. Crater width, depth, and ablation volumes were determined using an optical coherence tomography (OCT). Results: For all stones and energy settings, the Er:YAG laser produced deeper craters and larger ablation volumes than Ho:YAG laser. The Ho:YAG laser created wider craters during the multiple pulse process and the shape of craters was irregular. Conclusions: The Er:YAG laser is more efficient than the Ho:YAG laser for lithotripsy. The deeper craters produced by the Er:YAG laser is attributed to the high absorption of energy at its wavelength.

Glassy Materials and Light: Part 1

publicado na web em 05/02/2016 GLASSY MATERIALS AND LIGHT: PART 1. 2015 is the Year of Light, according to UNESCO. Chemistry has a close relationship with light and one of the materials that allows such synergy is glass. Depending on the chemical composition of the glass, it is possible to achieve technological applications for the whole range of wavelengths extending from the region of the microwave to gamma rays. This diversity of applications opens a large range of research where chemistry, as a central science, overlaps the fields of physics, engineering, medicine, etc., generating a huge amount of knowledge and technological products used for humanity. This review article aimed at discussing some families of glasses, illustrating some applications. Due to the extension of the theme, and all points raised, we thought it would be good to divide the article into two parts. In the first part we focus on the properties of heavy metal oxide glasses, fluoride glasses and chalcogenide glasses. In the second part we emphasize the properties of glassy thin films prepared by sol-gel methodology and some applications, of both glasses as the films in photonics, and more attention was given to the nonlinear properties and uses of photonic fibers.
