So they're not the James Bond-type devices that are used to cut people in half, and they're (very unfortunately) not light sabers. But you better believe that lasers are a ubiquitous part of daily life that you might not even realize you stumble upon.
First off, there are some more obvious ones -- laser scanners at the grocery store, for instance. Few of us actually realize that there are lasers making our DVDs play. Indeed, our DVDs are lined with microscopic bumps that will send information to a transmitter, which will then turn it into audio and visual form. But what reads these bumps, you ask?
That's right: lasers. The DVD player is outfitted with a laser that moves at a constant rate, reading the bumps of the DVD so you can enjoy watching your marathon session of "Deadliest Catch" from the couch. If you're going old school and listening to your old Backstreet Boys CD collection, you're also using lasers to read those. It may not be the most sophisticated or edgy use of a laser, but it is one you're using every day without thinking about it.
