The 650nm laser green is indeed the brightest hue in the apparent mild range. The laser was used to simplify this light to provide an output of 532nm, thus marking it as an environmentally friendly laser light. These beams are known for introducing some of the more commanding and intense laser beams that are built almost everywhere. The 650nm wavelength means that the high powered laser pointer emits light in a very narrow range around 650nm. Laser light at this wavelength is red. Different wavelengths reflect different colors of light. Other wavelengths and colors are shown below. Ordinary energy-saving lamps, fluorescent lamps emit light of various wavelengths, a wide range of wavelengths. The laser is very monochromatic and has a very narrow wavelength range, 650nm means that the laser pointer emits light in a very narrow range around 650nm. The wavelength of visible light ranges from 390 to 770 nanometers.
How does the light of a laser travel?
Green laser Pointer green laser pointer can have a variety of output power, even at low power, can be seen at night, so they are often used by astronomy enthusiasts to point out stars and constellations. 2, blue laser pen 473nm blue laser power is low and unstable, can not be widely used. It was not until later that more than 1,000 MW was developed. Laser products generally have a working temperature range, generally 0-40 degrees. There are also between 10 and 40 degrees. Laser pen in the case of too low temperature, such as lower than the working temperature, there will be incomplete laser start, the light is very weak, with the stability of the increase, the laser light will gradually become bright, until stable. But if the temperature is greater than the normal temperature, the laser light will drop, but the performance of the situation is used for a while to re-light and normal. Ordinary light is like all around the divergence, want to have a direction to emit light device, such as car headlights have the effect of concentrating light reflector. But lasers naturally shoot in one direction, but they also diverge at a small Angle, so the farther you go, the bigger the spot. Light through the medium will have a loss, is the reflection phenomenon, although the laser intensity is high, but in the air with the increase of distance will be weakened.
