Light Amplification by Stimulated Emission of Radiation LASERS Laser Fundamentals • A laser is a device that generates light by a process called STIMULATED EMISSION. • The acronym LASER stands for Light Amplification by Stimulated Emission of Radiation. • The light emitted from a laser is monochromatic. • Laser emit light that is highly directional. • The light from a laser is said to be coherent. Laser Operation: Excited State Energy Introduction Metastable State Spontaneous Energy

Laser dentistry is a relatively new form of dental care. Laser Dentistry uses lasers to perform surgery‚ prepare cavities‚ and harden dental resins. This use of lasers has allowed dentists to perform tasks with less pain and with improved results. There are many different types of lasers used in the dentistry field. Theses lasers included the argon laser‚ the diode laser‚ the neodymium: yttrium aluminum garnet (Nd:YAG) laser‚ the holmium: yttrium aluminum garnet (Ho:YAG) laser‚ the erbium: yttrium

The ruby laser‚ first invented in 1960‚ was the world’s first laser. Created by Theodore Maiman‚ the ruby laser is composed of aluminium oxide where some of the aluminium ions have been replaced with chromium ions. These chromium ions are what gives the ruby laser its red color. Its gain medium is a cylindrical crystal. A fully reflecting mirror and a partially reflecting mirror are placed at both ends of the cylindrical crystal. A high intensity lamp is spiraled around the cylinder to produce a

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

With such people as Barnett in power integration proved to be a very difficult task for civil right activists such as James Meredith. Barnett sought to block Meredith from entering the University of Mississippi in defiance of a Federal court order‚ this confrontation was one of the sharpest clashes between a State Governor and the Federal Government since the Civil War.

HISTORY OF INTEL PROCESSORS Today‚ computers are a part of our lifestyle‚ but the first computer that was used was developed at the University of Pennsylvania in the year 1946! It had an ENIAC (Electronic Numerical Integrator And Computer) processor. The reprogramming feature that is so extensively used today‚ was introduced by Alan Turing and John von Neumann with their teams. The von Neumann architecture is the basis of modern computers. From the development of the first microprocessor - Intel’s
