The laser is one of the most advanced tools we have in our civilization. Lasers are powerful enough to cut through a thick piece of steel, yet can be used in medical surgery. Lasers are used in the army, for guns, for range finding and a whole lot more. Most people don't know where the idea of the laser came from. The idea for the laser came from a machine called a maser. The maser was a tool that was able to strengthen, or amplify radio and light waves. The first laser was made in California

Laser surgery Lasers (The word laser is an acronym for light amplification by stimulated emission of radiation.) lasers were first introduced in 1960, The first successfully optical laser constructed by Maiman (1960), was a ruby crystal surrounded by a helicoilal flash tube enclosed within a polished aluminum cylindrical cavity cooled by forced air. The ruby cylinder forms a Fabry-Perot cavity by optically polishing the ends to be parallel to within a third of a wavelength of light. Each end was
Lasers and Their Uses We have all at some point in our lives used or seen someone use a laser. They are used in compact disc players for stereos or computers, laser surgery, laser printers, holography, cutting and borring metals, communication, bar-code scanners, etc. Over the past three decades' lasers have become a tool used daily by many people and they have become very useful in scientific research. As you can see lasers are a very useful and important tool which is why I have chosen this topic
LASER-PLASMA INTARECTION With the development of the technology of laser enabled the experiments using laser pulse with a high intensity of the order 〖10〗^22 W/〖cm〗^2. So now it brings the possibility of study the parameters of plasma as well as the atoms. The study related to the laser-plasma interaction involves the self-focusing, which is a very important factor to consider. Because the intensity of such a huge order came from it and high power laser and its applications, harmonic generation,
Laser commonly Known as Light Amplification by Stimulated Emission of Radiation. Laser is a phenomena in which a very narrow or thin beam of intense electromagnetic radiation i.e. light is emitted. Laser Beam Welding (LBW) is a welding technique or method used to join or link up pieces of metal with the help of a laser technology. The beam provides a concentrated/focused heat(infrared) source, allowing for narrow, deep, precise welds and high welding accuracy. The process is frequently/often used
When first discovered, lasers were thought to be the ‘cure all’ for modern scientific problems. Although many limitations have been realized, lasers are slowly improving many different aspects of our lives. From eye surgery to industrial precision cutting and fabrication to medical marvels like tattoo removal, surgery, and even destroying isolated cancer cells, lasers continue to be a behind-the-scenes tool for improving our lives. Many people have heard of the lasers, but few know that the term
How many of you know what laser surgery is? Perhaps, you have heard of this, but today lets learn about this procedure. The definition for laser eye surgery is, surgery used to correct vision in people who are nearsighted, farsighted, or have astigmatism. Lasik surgery is an outpatient procedure, and there is no overnight stay. Before you begin any kind of surgery it is beneficial you speak to your eye doctor. Set up an appointment to see what kind of laser surgery would be right for you
Laser Technology Abstract: A laser is a electron device that produces a very narrow, powerful beam of light. The essential components of a laser include an active medium, an energy source, and an optical cavity. The optical cavity itself is enclosed by the resonator which has a mirror at each end. The energy that is put into the laser causes the atoms of the active medium to be excited to a higher energy level. When these atoms relax back down to their ground level they emit photons, which
Benefits of facial laser treatment: • The primary advantage is that the laser treatment is an absolutely harmless and painless method of facial. It does not involve going under knife and bearing the pain. • The laser procedure is much faster than the surgical operations. Moreover, regular visits are also not required to derive benefit of the treatment. • The time required for recovery and recuperation in laser treatment is less than that required for surgery. Considerations: These three factors

The green laser is used due to its incorporation of light in murky waters is the slightest at these wavelengths. One laser is applies which creates an infrared laser. A frequency double then changes the frequency of a fraction of the beam by a aspect of two , resulting in a green light laser. Some Advantages and Disadvantages of LADS include: Advantages Disadvantages ? A quick and effortless
Laser Crowd Scanning is and amazing visual effect at most live entertainment shows, especially concerts. But, there is a bunch of safety factors that go into play before the lasers can or may be used. Some of these safety factors include, knowing where the free space is amongst the venue, understanding the angle of the beams and knowing that the safe zones aren’t amongst the areas where a person in the crowd could be in line with the beams. Before even wasting the time and effort to setup the lasers
game? A perfect pair of soccer shoe for his game. Shoes that give them full control over the ball with a perfect accuracy that help him to soccer a goal. In my opinion, Nike did an excellent job in making their advertisement about their new T90 III laser soccer shoe. The main theme of the Nike – T90 III shoes in the advertisement, “Nike – Hit the Target,” is no matter how good you play or how famous you are in the soccer world. You still need a pair of shoe that will help in gaining control over the

Introduction In the world of communication, lasers can be very helpful in transporting a variety of information across the planet. In this experiment, we decided to advance our knowledge about lasers and perform more tedious activities with them. Instead of shooting lasers through a gelatin substance and reading angles in which they reflect, we were going to step it up a bit. This time our final goal was to be able to verbally communicate through space using a laser. Photonics is described as science and
is to inform the reader of all the things that take place when you watch a movie on a DVD player, starting with the CD itself. The laser reads the CD and converts it to the final product of what we see and hear. Most CDs are made from polycarbonate plastic. This polycarbonate is a tough material that helps to prevent scratching. Scratching of a CD causes the laser, which reads the spiral data, to jump off track, allowing the CD to skip around and to distort whatever you are watching or listening
Gordon Gould proposed laser action, then not long after 4 years, in 1960, first laser was build by Theodore Maiman. Besides that, Gordon also derived the word laser from “light amplification by the stimulated emission of radiation”. The laser developer look amplification is very important as a step to build a laser, so these people make one advance to develop amplifiers from semiconductor laser to be used as light sources. This is because of semiconductor have high gain. Laser made up with high gain
