When we want to choose a good laser pointer, these factors we may have to take into consideration: LD (light bulb) quality, lens quality, laser crystals quality, and the laser power which will affect the quality of laser beam. So please note the following points when choosing laser pointer:
There are hundreds of variations on a simple laser pointer. However, when choosing which to use, a couple of things must be kept in mind. First, choose an appropriate intensity of laser. Even though there are green lasers that can start fires, there is no way burning a hole in a projection screen will be good for a presentation. Stick to low intensity lasers unless you specifically need higher intensities (for stargazing, for instance). As far as functionality is concerned, smaller and lighter laser pointers are easier to use and more compact, which can add to the effectiveness of a presentation. Stick to small lasers, but don't sacrifice battery life for a smaller laser pointer.
Choosing a good Laser Point and using it in professional fields such as military,astronomy, scientific research, medical or laboratory experiment, while people still need pay high caution while using it for work. Anytime using of high power green laser pointer should pay high attention and then you can really have a good result on your work.
