Laser - Wikipedia- fiber laser review article ,Quite often, the fiber laser is designed as a double-clad fiber. This type of fiber consists of a fiber core, an inner cladding and an outer cladding. The index of the three concentric layers is chosen so that the fiber core acts as a single-mode fiber for the laser emission while the outer cladding acts as a highly multimode core for the pump ... Electrospinning - WikipediaElectrospinning is a fiber production method that uses electric force to draw charged threads of polymer solutions or polymer melts up to fiber diameters in the order of some hundred nanometers. Electrospinning shares characteristics of both electrospraying and conventional solution dry spinning of fibers. [1]

The 1450-nm diode laser is effective for the treatment of facial acne as well as for improving the appearance of scarring. 24 The nonablative laser has been shown to dramatically and safely improve inflammatory facial acne by partially damaging sebaceous glands to reduce sebum secretions. 25 The 1450-nm diode laser has demonstrated greater scar ...
The AN/SEQ-3 Laser Weapon System or XN-1 LaWS is a laser weapon developed by the United States Navy.The weapon was installed on USS Ponce for field testing in 2014. In December 2014, the United States Navy reported that the LaWS system worked perfectly against low-end asymmetric threats, and that the commander of Ponce was authorized to use the system as a defensive weapon.
The high incidence of muscle injury has caused an increase in studies related to physical therapy resources that are involved in the injury healing process.44 Among the most widely used, LLLT is noteworthy, as it triggers the production of adenosine triphosphate (ATP),45 enhances the migration of satellite cells and fibroblasts, and promotes ...

Stick electrodes and shielded gas welding are supported, and the maximum current output by the inverter converter in both modes is 200 amperes.
A good review of such work can be found in Hastie et al. (see also §3c). A related technique to SCoTLASS adds a penalty function to the variance criterion maximized, so that the optimization problem becomes to successively find a k , k =1,2,…, p , that maximize , subject to a ′ k a k =1, where ψ is a tuning parameter [ 29 ].
Laser image based processing technique. The detection of the cracks in the structures by using the Laser image in the image processing technique is reviewed in this section. MostafaRabah et al. have proposed a crack detection system with a high spatial resolution of imaging and the excellent capability of measuring the 3D space by laser ...
The name National Ignition Facility refers to the goal of igniting the fusion fuel, a long-sought threshold in fusion research. In existing (non-weapon) fusion experiments the heat produced by the fusion reactions rapidly escapes from the plasma, meaning that external heating must be applied continually in order to keep the reactions going.

They reported good quality welds with tensile strengths close to parent AA1050 when laser power was low enough to prevent full penetration into Al. Laser welding of low carbon steel DC04 and aluminum alloy AA6016, both in 1 mm thickness, was investigated by Guan et al. using a fiber laser. The focus of their study was to probe the impact of ...
Having round-the-clock access to high-quality health information can help you take control of your health and discover ways to live well. But fake or misleading health information can be scaremongering and even dangerous.

With radiofrequency ablation of the GSV there is complete obliteration in 85% after 2 years with recanalization in ≈11%. 102 However, 90% of patients treated with radiofrequency ablation are free from saphenous vein reflux, and 95% of patients report satisfaction and improvement of symptoms (regardless of the technical success). 102 Laser ...
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light.

A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing.
Electronics collect dust over time. Laser printers are especially prone to dust and debris. Because laser printers use toner cartridges, the mechanisms can become clogged up when ink toner accumulates in tight areas. Cleaning a laser printer can restore the machine to its original operability. Use these steps to properly clean your printer.

Glass fiber optic connector performance is affected both by the connector and by the glass fiber. Concentricity tolerances affect the fiber, fiber core, and connector body. The core optical index of refraction is also subject to variations. Stress in the polished fiber can cause excess return loss. The fiber can slide along its length in the ...

In article number 2100620, Yating Wan and colleagues describe a laser theory, beyond the customary quasi-mode approximation for treating resonator outcoupling, for understanding the physics underlying spectral narrowing to Hz-level, spontaneous-emission limited lasing linewidth. This theory will serve as an analytical tool for parametric ...
