Optical limiting performances of acid blue 29 are investigated under irradiation by a 35 mW continuous wave He–Ne laser. The optical limiting behavior is investigated by using transmission measurement through samples with different concentrations. Our results show that the optical limiting efficiency is concentrations dependence. Induced self-diffraction patterns are observed at relatively high...

H. M. Shang National University of Singapore Department of Mechanical Engineering 10 Kent Ridge Crescent 119260 Singapore Abstract. We have developed a measurement method to evaluate deformation of a metallic membrane (thickness 2 mm) in a micro-radiofrequency switch. The method is based on a modified Michelson interferometer incorporated with optoelectronic devices including a He-Ne laser, con...

The application of He-Ne laser technologies for description of articular cartilage degeneration, one of the most common diseases worldwide, is an innovative usage of these technologies used primarily in material engineering. Plain radiography and magnetic resonance imaging are insufficient to allow the early assessment of the disease. As surface roughness of articular cartilage is an important ...

Synthesis of copper-telluride nanowires has been carried out using template-assisted electrodeposition technique. The polycarbonate template is supported on a copper substrate. The synthesized nanowires were characterized using scanning electron microscopy (SEM) and X-ray diffractometer (XRD). The SEM image has confirmed the satisfactory deposition of the CuTe nanowires having 100 nm diameters ...
