A Laser's Practicality - By: Stitch Rojas

The laser is perhaps one of the more impressive tools that is in existence today but did you realize that when it was first created, it was not necessarily known what it could be used for in practical terms? In fact, many people considered the laser to be a solution that was waiting for the problem to occur. Although it did take several decades before a real solution to the laser was put into place, today it finds itself in many different industries. Here are some of the common uses of lasers and how it has benefited mankind in so many different ways.

One of the primary uses of laser is in industrial settings and it can be used in a number of different ways, depending upon which industry is being used by. One of the primary ways in which lasers are used within industry is for measuring purposes. The reason why it is used in this way is because it gives accuracy that is far beyond anything that was in existence beforehand. This is especially beneficial in today's industry, were very specific parts must be manufactured to exact dimensions. For example, a spirit laser level is something that is used in many industries. When the laser beam is set at level, it can sweep across the surface in order to determine that the services level as well. This is used in construction in many cases, helping to determine if a wall was straight or to strike a line where a ceiling will be installed. The mining industry also makes good use of lasers, as it can help to keep the drilling directions stable and on course. That isn't even to mention the laser cutter and other specialty tools that did not exist several decades ago.

There is also the use for lasers in communications. Fiber optics used lasers on a regular basis, due to the fact that it has a much greater bandwidth than copper cable. This gives the opportunity for the data to be transmitted from one area to another with very little loss of down along the way. It can also help to limit the amount of cross talk that is heard, where you may end up hearing another conversation when you're talking on the telephone. This was a regular occurrence several decades ago but now, thanks to fiber optics, it is rarely ever occurrence.

One of the ways that lasers are used is in medicine. Various types of surgery use laser due to the precision that it offers. Although we could cite a number of examples, such as brain surgery, it is more commonly known for laser eye surgery and for the removal of tattoos and birthmarks. These are very specialty items that would require specialty schools along with them. All of these tools, however, make use of the basic laser that was developed quite some time ago. Although it has been improved on, many of the features of the laser are still very similar to what they were upon its inception.
