Thanks to the elite professionals of laser diode technology, various kinds of laser pointers are available in the market place. Owing to continuous development of laser diode technology, not only various kinds of laser series are available but also wide applications of laser pointers have been explored at the same time.
In the very beginning of invention of laser pointer, red laser pointer and low power green laser pointer are usually used for presentation in scientific research, teaching, lecture and speech etc. anyway, laser pointers are merely used in our daily life, and most are which are used for entertainment. People will choose a green laser pointer with an output power ranging from 100mW to 200mW to seek enjoyment such as pop balloons, light matches, burn plastic and papers, melt rubber, cut electric tapes and so on. However, green laser pointers have got wider applications in our daily life.
Laser Pointer is a wonderful gadget for presentation, and it also plays an especially important part in astronomy and military field. For example, green laser pointer can be used to watch stars and point anyone of celestial objects in the night sky. The bright beam of green laser pointer can scatter quickly into atmosphere layer, and the beam can reach the objects only in seconds. The using of green laser pointer has made it much easier for astronomers to watch celestials, and people have no longer need to wave arms and explain which objects they are pointing at. The beam is so bright that people can just feel the laser pointer is nearly touching the star.
Usually a green laser pointer ranging from 5mW to 150mW can be used in astronomy, and different conditions have decided the output power that you are in need of. Whenever pointing green laser pointer into night sky, people should have a clear check if there are any air craft, or it might cause serious air crash for your carelessness. Taking care of human eyes is also an important thing that should be paid attention to, and then you can really have a good time with green laser pointer.
