laser pointer

Technically speaking, laser pointer laser is an amplified light by stimulated emission of radiation. Inside every laser pointer device are small chips that are used to create radiation when electric current passes through them. These are called laser diodes which are laser themselves. Currently different colors can be emitted through a handy device called laser pointers and these products are out in the market. The colors of each device are achieved depending on the alignment of the laser diodes inside it for a certain frequency of light measured in nanometer (nm). The color of lights that are now available for sale are red (671 nm), yellow (593 nm), green (532 nm), blue (473 nm), and violet (405 nm). With so many colors to choose from, it cannot be avoided that one color will become superior among the others. And in this case, the green laser pointer has the most sales in any brand. The green laser pointer has a wavelength that is not too wide like infrared and not too thin like the ultraviolet ray. This gives the laser the green light that is perfect for any dark lighting. The light of the green is so vivid that the beam looks like a solid green rod especially when dust particles pass through it. The green laser has a super powerful light that you can purchase a device with a power output of 5mW up to 100mW! But be careful because with this so much power, the laser can burn paper, pop balloons, and even light matchstick. This can be dangerous when focused in the wrong object so you have to be responsible once you have this kind of device. This gadget with the green light is powerful enough that it is used by people in many areas such as astronomy, military, search and operations, and many other fields.
