With the continuous development of laser diode technology, different types of green laser pointer are available online to meet all possible laser human needs. So which one is the perfect one for you? There are some helpful tips you can consider before making a purchase. This basic question has helped you get a clear idea of what type of green laser you like best. For presentations, business meetings, teaching, or simple presentations in PowerPoint, a laser pointer with a lower power output is usually sufficient. For military, astronomical or scientific research, such as stargazing, rescue, camping pointing, etc., the green laser diode with higher output power should be selected, because the high power green laser pen can still make the laser beam visible.
The range and visible distance of any laser depends on several different factors. The first is the output power (mW), followed by the color of the laser. Both are important factors determining the visible distance of laser beam. Generally, green lasers are about 7 times brighter than any other laser at the same output power, so green is best suited for illumination at the same power. The laser beam is known for its powerful beam strength, its ability to maintain a straight path over infinite distances and form a tight spot of light when it hits an opaque object.
