    Abstract: To clarify the formation mechanism of periodic nanometer-size cavity structure of a borosilicate glass sample, the free electron density around the exit surface was investigated when it exposed to intense femtosecond laser radiation. The electron density near the edge of the crack on the surface was estimated to be 1020-1022 cm-3. From this result,... Show More

    Abstract: In the field of electronics, one of the objectives of current research is to integrate numerous components in increasingly smaller volumes. Reducing the cost of manufacturing components requires integration and collective manufacturing. This paper mainly focuses on the design and the main steps of the micro-fabrication of a transformer with magneti... Show More

    Abstract: Power quality is a significant issue that has become increasingly important to both electric power utilities and their customers because of financial losses caused by insufficient. In this work, the Fourier transform (FT) has been exploited for the statistical investigation of the disturbances affecting the electrical distribution networks (HTA) in... Show More

    Abstract: Rare-earth-doped optical fibers are one of the most promising solid-state lasers. In these fiber lasers, a cladding-pumping scheme using double-clad fibers is utilized to increase the overall conversion efficiency of pumping light. To maintain acceptable beam quality, the low-numerical aperture large-mode-area fibers is effective for the double-cla... Show More
