A laser pointer is a type of laser in a movable, pen-shaped form that is normally of design to be held by hand. Laser pointers are most generally used to display a point of light that could show things of curiosity, for example during a presentation. On the last few years laser pointers received attention in the public press and roused some public curiosity. As a consumer product, laser pointers are decided to be harmless when its used for their designed end use. Sadly, however, the laser pointer can easily be used incorrectly.
Green laser pointers, (also called DPSSFD, diode pumped solid state frequency-doubled), are much more proper complicated than the standard red ones, since laser diodes are not familiarly handy in this wavelength range. The green light is created in an non direct process, beginning with a high-power (commonly 200-300 mW) infrared AlGaAs laser diode performing at 808 nm. Like all lasers, laser pointers should never be projected directly in the the eyes of a person or animal or indeed any moving vehicle in which the driver or pilot could be distracted. The output of laser pointers is generally limited to 1mW or 5mW in order to aid collateral damage to the retina of human eyes
The technical knowledge of the green laser pointer is totally different from a red pointer. Because it is so much brighter than the red lasers, a green pointer could be seen at a much farther distance. This of course is good if you are still trying to signal someone away. Experts say that a direct shot to the eye from a laser by 15 mW could incessantly damage the eye within a fraction of a second. The risk becomes more big with more proper powerful lasers, which are readily that you can use on the internet at this day. Get on the 21st century with your laser pointer. Get a green laser pointer, on the other hand do remmeber the risks of using it. The utilize of assurance goggles when working high-powered lasers is much suggested.
If you want to find and compare some of these laser pointers I recommend that you do a search on google or go to amazon and compare prices, they are very useful for teachers and for people that make presentations.
