What are LASERs Used For? The uses of lasers as we head into the new millenium are too numerous to mention. Lasers perform tasks as highly diversified as removing a cancerous tumor to laying bricks in a straight line to sending your voice across the country when you talk on the phone. Every day there are more and more jobs that require lasers -- and people to fill those jobs. If you have a highway near you that is under construction, chances are the engineers are using LASER's to layout the new highway. Police will use LASER's to see how fast you are travelling on the new highway. LASER's can be used to restore paintings that are centuries old -- removing oxidation and grime without touching the actual paint. They are used at your supermarket check-out, scanning your purchase. You can have an old tatoo removed using a laser, or have blemishes and age spots removed. LASER's have been fired to the moon and bounced back using equipment left there by the Apollo astronauts. They entertain us with LASER light shows. We enjoy music on our CD's, movies on our DVD players and store and retrieve information from our computer's CD-ROM, all though the use of lasers. We then print out our information with LASER printers. Did you ever have one of the frozen "BBQ" hamburgers for lunch? Did you notice the BBQ grill marks on the hamburger? They are not put there from a BBQ, they are put there by passing the hamburger over laser beams before packaging! If you have a late model car, all of the body parts were welded together using LASERs attached to robotic arms at the factory.
And the list goes on and on. As you can see, LASER's have become a very important part of all of our lives. And its use will continue to grow well into the next century and beyond.
