Laser eye surgery has enabled millions of people to throw away their eyeglasses. Now several medical technology companies are hoping that lasers aimed at the feet will allow millions to take their socks off‚ even in public. The target is toenail fungus — an infection in an estimated 10 percent of American adults‚ or 23 million people — that causes toenails to become thick‚ yellow and fetid. If these lasers‚ which recently completed small clinical trials‚ work‚ they will represent a new way

Lasers are originated as an acronym for "light amplification by stimulated emission of radiation". A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. Numerous logical‚ military‚ restorative and business laser applications have been produced since the creation of the laser in 1958. One of the most common uses of lasers is laser hair removal. The concept of laser hair removal was invented by Dr. Rox Anderson

an Erbium Doped Fibre Amplifier (EDFA) by using a tuneable Long-Period Grating ) (LPG). The gain spectrum of an EDFA at a wavelength of ) 1530nm was equalized from 5.2dB peak-to-peak to 2.3dB peak-to-peak. The LPG was fabricated by using an excimer laser and a metal mask. By means of a novel technique that enables one to tune the peak attenuation of the LPG‚ the gain equalizer can operate over a wide range of pump power.

wavelength of the laser light they use the closer they can make the grooves and the more information they can get on the disk. Also notice however that the track pitch decreases more rapidly than the wavelength of the lasers in the above table‚ this is because you can also reduce the track pitch if you increase what is called the Numerical aperture of the lens you use. In fact how much information you can store on a disk depends on how small you can get the "spot size" of the laser beam and the radius

INTRODUCTION The current ultramodern technologies are focusing on automation and miniaturization. The decreasing computing device size‚ increased connectivity and enhanced interaction with the physical world have characterized computing history. Recently‚ the popularity of small computing devices‚ such as hand held computers and cell phones; rapidly flourishing internet group and the diminishing size and cost of sensors and especially transistors have accelerated these strengths. The emergence

Laser eye surgery has ended up more secure throughout the years‚ because of better innovation and more experienced specialists. Most patients experience some reactions‚ however‚ whether that is dry eye or redness after surgery. Be that as it may‚ these have a tendency to be transitory. A few dangers‚ for example‚ that of radiance‚ could be changeless‚ on the other hand. Yet there’s a considerable measure in your energy to bolster the accomplishment of your Eye Surgery. Here are a few variables you

Moreover‚ in recent years‚ modern technologies developed some substitutes such as make-believe firecrackers‚ some tricky balloons are being produced and used in some wedding ceremonies instead of fireworks. Furthermore‚ we cannot ignore the laser beams while talking about the new players in this industry. These substitutes may cause the reduction of sales of fireworks. When a company is stuck in a situation that we mentioned above; there are two absolute ways: first one is running away which
