This cuts down on the cost of manufacturing because a laser never gets dull.
Computer manufacturers use lasers to treat semiconductor chips. They also use the laser to do precision welding in glass tubes such as resistors, diodes, transistors, and many other microchips. This has enabled computer companies to decrease the size of the computer and increase the processing speed of the computer.
.
Mining.
Another area in industry where lasers are used is mining. They use the laser to precision digging and drilling. Mine safety people use lasers to test shafts in the mine for cracks. The laser shoots the beams in all directions and from that a computer can tell the size, shape, and if there are any cracks in the tunnel or digging area. This is a very valuable tool because it cuts down on the chance of an accident.
Communication.
The laser has revolutionized communication. Because of the high frequency of laser light it can carry approximately 1000 times the TV channels as carried by microwaves. This makes lasers the ideal tool for space communication. Lasers are now being used for communication on earth such as telephones and computer systems. This is made possible by low-loss optical fibers also known as fiber optics. With use of fiber optics, signals can be sent up to 100 kilometers before you need a signal booster compared to the current system where you needed a signal booster every 1.5 kilometers. .
Photography.
Lasers can produce a type of three-dimensional image called holograms. Holograms are made by exposing laser light to a piece of film. The object that is being holographed strews the laser light. The piece of film being holographed is also being exposed to light coming directly from the laser this is the reference beam. These two beams of laser light become disharmonious with on another because they are traveling from different paths. The film then records the interference pattern, between the two light beams, which is the hologram.
