Laser is the device which emits light provided from the emission of photons. The light which is emitted from the laser is known for its high level of coherence, which is not typical for other technological inventions. The coherence of the laser wave is expressed through the output of the device, which is called a "narrow beam" or a "pencil-beam". The laser beam can spot very little spots of a place or an object or can be attached to a beam with low divergence to be used for spotting objects in a long distance.
Since the history of laser has begun there are a lot of innovations which grow their number year after year. They are used for optimizing different goals of laser performance. A little part of them are the maximum power efficiency, maximum average output power, minimum output duration and, of course, minimum cost.
There are different types of laser pointers, which are different from each other thanks to the color of the light they emit and their wavelength. The most common and simplest of them is red laser pointer, which is powered by a battery. It has first bee used in the early 80's and they were much larger than now are. The longest wave which they can produce is 671 nm. Other types of laser pen are the yellow laser pointer, and the blue and violet laser pens which appeared in the latest years.
One of the new versions of laser are green laser pens. The High Power Laser Pointer is about 60 times brighter than a red laser and because of the green light it produces it can be much more easily noticed. That's why having a green High Power Laser Pointer is the best way to stand out. The 532nm High Power Laser Pointer is much more noticeable than the 650 nm red laser pointer and in the dark, unlike the red laser, the beam of the laser can be seen itself, but not only a laser point. That's why this device is good for astronomy, and especially for sky pointing. And this is not all. They are completely suitable for bird watching, hiking, camping, tour guides and so many other nature activities. It also gives the opportunity to make laser shows anytime and anywhere. And what's the most interesting the 532nm green laser pointer can be used to ignite matches. The device of the new generation is suitable for any activities people can do in daily life.
