Crazy Things That Lasers Can Do

_____________

You Use Lasers:

Ever been curious about what lasers are used for? Besides our favorite use of cutting metal, of course, lasers have many other amazing uses.

If you’re like most people, you are probably completely unaware of the fact that you use lasers on a daily basis. For example, any time you flip on your television, lasers are being used in your remote, in the screen, and in the DVD or cable.

Open up your laptop and take a look at your screen. Lasers!

Lasers transmit data packages, create memory storage, and burn (literally) information into CDs. Need to send something to your printer? Most printers now use laser technology for increased printing precision.

But it doesn’t stop there. Pick up your mobile phone and make a phone call. Yup, transmission of data and mobile calls use lasers too. Need to stop at the supermarket? Lasers are used to scan barcodes, informing computerized systems of the item number just scanned.

Perhaps the most notable and revolutionary use of lasers is the advancements lasers have brought into the world of medicine. Lasers are able to perform minute incisions with minimal bleeding, swelling, and bruising, as well as procedures that would be impossible with any other equipment.

Naturally, we know that you’re aware lasers are used for precision cutting metals. But did you also know they are used to temper glass, cut through plastics and even fabric? In fact, the clothing you have on right now was very likely cut by a laser beam!

Lasers are also used for measuring and surveying land mass and polar ice caps, locating and targeting enemy locations in military operations, fingerprinting diamonds with minute serial numbers, and creating holograms. And no, there really is no field of work in which lasers are not used in one capacity or another.

Most amazing of all, lasers themselves are a fairly recent invention--they are even a couple of years younger than the original internet. Lasers are now used in virtually every industry, in nearly every country, filling hundreds of various roles.
