Hey everyone, I had an Advanced comp assignment to write an article and since I am in the hobby of lasers I chose to write about them.


An Unknown Hobby…Until Now


Recently, a previously unknown hobby hit the World. In previous years this hobby was not well known, and many people today still do not know anything about it. Recent technology allows lasers to reach much more power than in previous years. Because of this, people all over the globe have started to build and sell of high-powered or unique wavelength lasers. To choose the right first laser, one must decide what wavelength he or she desires, how much power he or she wants in their hands, safety issues, and his or her local laws.


To choose a wavelength one must first choose what he or she wants their laser to do. For instance, if someone wants a laser just for show, he or she might choose a 532 nanometer wavelength, green, since the human eye can see that wavelength better than any other. Because the human eye picks up the 532 nanometer wavelength the best, the laser would not need to be very powerful to emit an intense beam. On the other hand if a person wanted a laser for burning items, he or she might choose a blue wavelength like 445, 447, or 405 nanometers as those produce the most energy per milliwatt of power. In the end to decide what wavelength a person wants, he or she must first decide what they want their laser to accomplish.


Choosing the right amount of power has the same importance as choosing the right wavelength. Those new to this hobby should start out with a low power laser such as five to fifteen milliwatts. At that power the laser will not cause any damage, but it will still be highly visible. With any wavelength, a hundred millwatt laser will smoke leather, pop balloons, and in some cases light matches. Lasers with those types of powers generally should not be used indoors as the light emitted from such powers can blind people. For one to choose the right power, he or she must first ask themselves if they want a laser to show or to burn.


One wishing to get into the laser hobby must take into consideration the safety of himself and those around him. Today, lasers have the ability to turn retinas into useless bits of flesh in less than a second. Because the dangers of blindness, anyone who operates or watches someone operate a laser over one-hundred milliwatts needs safety goggles to protect against the wavelength of the laser. Safety glasses reduce the power of a laser by several hundred milliwatts, making lasers much safer to view indoors. Also, those who have small siblings or children need to buy a laser that either has a key lock or a code that once entered the laser turns on. If one takes these safety precautions when purchasing a high powered laser, himself or anyone else will have a significantly lower chance of obtaining injuries from the laser’s beam.
Anyone who wishes to get into the hobby of high powered lasers must also take into consideration his or her national laws when purchasing lasers. America has some of the more lenient laser laws that only allow the importation of five milliwatt lasers and below. However, anyone can own a laser of any power as long as it meets the Food and Drug’s rules. On the other hand, no one in Australia can own a laser over one milliwatt no matter what safety features it has. Because every country has different laws, one must check his country’s laws before purchasing a laser.


After considering safety issues, his or her country’s laws, and the power and wavelength he or she wants, they will discover the world of lasers. Even though this hobby has many things to consider before purchasing a first laser, once that first laser gets into the hands of a new laser hobbyist, they will most likely fall in love with them. Though dangerous, the world of lasers ignites the lost child in everyone. If someone new to lasers uses his or her lasers with respect, they pose no threat to anyone. With the proper precautions, anyone can enjoy this unknown hobby.
:thanks: (if yall survived my paper :p )
