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

display involving analog to digital conversion and laser bit communication was constructed. The exhibit also demonstrates how more bits can be used to communicate a more accurate signal. For this task‚ an audio information source (CD player) produces a signal that is converted to digital information. This information will then be sent to a receiver using laser light switching on and off to communicate zero’s and one’s. The receiver will pick up the laser light and convert the digital information back

Learn how to create laser graffiti This week‚ I met with the gentlemen of Graffiti Research Lab Vienna‚ aka‚ GRLv‚ and they were kind enough to break it on down and show me how to set up a laptop‚ camera‚ projector‚ and laser to be a nondestructive and awesome graffiti tool. The following is copied directly and without edits from the README file as found in the Laser Marker zipfile that you can find in the sidebar at http://graffitiresearchlab.at.

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

|LASER ALIGNMENT THEORY Modern optical metrology uses precise lines and planes in space from which measurements are made. Because this method creates these features using light it has become known as optical tooling. The 35 year old historical development and current technology of laser instrumentation as used in optical tooling is discussed in detail. This includes the how the measurements are made‚ applications‚ and the technology of alignment lasers and position sensing targets developed for

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

played with lasers? We have all loved the laser fights in movies like Star Wars. Who wouldn’t want wield a laser around while fighting an enemy. Did you know that the term laser came from an acronym meaning “light amplification by stimulated emission of radiation.”? It should actually be all capitalized but for simplicity it isn’t. The first working laser was actually demonstrated by Theodore Maiman at the Hughes Research Laboratories back in 1960. The strength of early lasers was measured
