This infrared laser pointer essentially consists of a laser diode, a control unit and power supply, consisting of a small laser generator. The use mainly of the power of the laser diode to produce a single wavelength excitation resonator beam, that is, laser pointer strength. For lasers, the power is a measure of the release of an important indicator of energy within the unit of time. Laser pointer is usually available in the market, their power range from a few milliwatts to several hundred milliwatts 00.00. The higher the current, the more energy per unit time of the laser output unit. Under normal circumstances, the body can withstand the laser power of 0.4 mW, high power laser pointer beam on the eyes can lead to retinal damage and can even lead to permanent vision loss. Prolonged direct contact with the skin can cause burns.
