light waves in a laserbeam are aligned with each other‚ while the light waves from a flashlight are arranged randomly. The significance of this difference will become apparent as you read about the nature of light. Lasers come in all sizes—from tiny diode lasers small enough to fit in the eye of a needle to huge military and research lasers that fill a three-story building.And different lasers can produce many different colors of light. The "light" produced by carbon dioxide lasers and neodymium lasers

resonant snubber is presented in this paper. The passive snubber circuit‚ which is composed of two diodes‚ two capacitors‚ and one coupled inductor‚ ensures a zero current turn-on and zero voltage turn-off conditions for the power switch‚ and alleviates the reverse-recovery problem for the output diode. Moreover‚ with the proper design of the snubber circuit‚ the power switch and output diode can be softly switched in a wide load range. The operating principle and performance analysis of the

1. Introduction Blu-ray is a new optical disc standard based on the use of a blue laser rather than the red laser of today’s DVD players. The standard‚ developed collaboratively by Hitachi‚ LG‚ Matsushita (Panasonic)‚ Pioneer‚ Philips‚ Samsung‚ Sharp‚ Sony‚ and Thomson‚ threatens to make current DVD players obsolete. It is not clear whether new Blu-ray players might include both kinds of lasers in order to be able to read current CD and DVD formats. The new standard‚ developed jointly

1. INTRODUCTION Energy plays an important role in human activities. The utilization of fossil fuel based energy resources has increased the impact on the global environmental issues such as CO2 emissions that contribute to global warming and a drastic climate changing. The need of exploitation of new sources such as renewable energy (RE) becomes crucial. The combination of multi-source renewable energies at the distribution stage and the proper energy management will definitely reducing the cost

Abstract This paper will discuss the design of an FM receiver. It will begin with a brief historical backdrop of FM broadcasting and its use in society. It will continue by providing the necessary mathematical background of the modulation process. Furthermore‚ it will enumerate some of the advantages of FM over other forms of modulation‚ namely AM. Finally‚ the paper will discuss the design of a basic FM receiver as well as introduce some circuits and circuit components which the reader may

Power Supply Regulation DC-DC voltage converters are often used to provide a regulated voltage supply from an unregulated voltage source. Unregulated voltage sources can be rectified line voltages that exhibit fluctuations due to changes in magnitude. Regulated voltage supplies provide an average DC output voltage at a desired level (3.3 V‚ 2.5 V‚ etc.)‚ despite fluctuating input voltage sources and variable output loads. Factors to consider when deciding on a regulated voltage supply solution include:
