Summary
Chalcogenide glass fibers were fabricated for CO(2) laser transmission. Crucible drawing produced lower loss fibers, achieving 1.7 dB/m at 10.6 microm, enabling efficient laser power delivery.
Area of Science:
- Materials Science
- Optical Engineering
- Glass Fiber Technology
Background:
- Chalcogenide glass fibers are promising for mid-infrared applications.
- Efficient transmission of carbon dioxide (CO(2)) laser power requires low-loss optical fibers.
- Fabrication methods impact fiber performance and structural integrity.
Purpose of the Study:
- To prepare and characterize chalcogenide glass fibers for CO(2) laser transmission.
- To compare the effectiveness of crucible drawing versus preform drawing methods.
- To determine the lowest transmission loss achievable and assess laser power handling capabilities.
Main Methods:
- Fabrication of GeAsSeTe, GeSeTeTl, and GeSeTe glass fibers using crucible drawing and preform drawing.
- Measurement of transmission loss spectra using the cut-back method.
- Evaluation of CO(2) laser power transmission through a 1.5-m fiber.
Main Results:
- Crucible drawing yielded lower transmission losses compared to preform drawing, attributed to reduced interfacial imperfections.
- The lowest transmission loss achieved was 1.7 dB/m at 10.6 microm for a GeSeTe core/GeAsSeTe cladding fiber.
- A 1.5-m fiber successfully transmitted CO(2) laser power, achieving an output of 2 W (2.2 kW/cm(2)).
Conclusions:
- The crucible drawing method is superior for fabricating low-loss chalcogenide glass fibers for CO(2) laser applications.
- GeSeTe core/GeAsSeTe cladding fibers demonstrate excellent performance for mid-infrared laser power delivery.
- These fibers show potential for efficient and high-power transmission of CO(2) laser radiation.

01:22Fiber Reinforced Concrete
Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...
02:42Ionic Crystal Structures
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

01:22Types of Cement II
Portland blast-furnace cement is made by blending Portland cement clinker with granulated blast-furnace slag, which accounts for 25 to 65 percent of the cement's weight. Despite its similarities to ordinary Portland (Type I) cement in terms of fineness and setting times, its early strength is lower, though it achieves comparable strength later on. It's particularly suited for mass concrete structures and marine environments due to its lower heat of hydration and superior sulfate resistance.
01:21Polymer Classification: Crystallinity
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

01:10Silica Gel Column Chromatography: Overview
Silica gel column chromatography is a technique for separating compounds using a column packed with silica gel as the stationary phase. This method relies on differences in the polarity of compounds. Based on their polarities, compounds move between the stationary phase (silica gel) and the mobile phase (the solvent), forming discrete bands in the column.
Polar components tend to bind strongly to the silica gel, causing them to move slowly through the column. In contrast, nonpolar compounds...

01:21Aggregate Cement Ratio
The Aggregate Cement ratio refers to the weight of aggregate divided by the weight of cement in a concrete mix. Altering this ratio has profound effects on the concrete's properties. This ratio plays a pivotal role in determining the strength, workability, and durability of concrete. When the Aggregate Cement ratio is higher, the mix is leaner, meaning it has less cement paste to lubricate the aggregate, potentially making the concrete less workable. Such mixes, known as lean, enhance the...
