What are the characteristics of the Quartet laser pointer?
The high brightness high powered laser is mainly due to its high beam concentration. The high brightness of laser is also the embodiment of its high concentration of energy. When the lens is focused, temperatures of thousands or even tens of thousands of degrees can form near the focus. This property makes it possible to process almost any material. The color of light is determined by the wavelength of light, and light has a certain range of wavelengths. The narrower the wavelength range, the better the monochromaticity. For ordinary light source, the color displayed will be more complicated due to the wide spectrum width and wide frequency range.

Light from ordinary sources travels in all directions at a wide Angle of divergence. Lasers, by contrast, have a very small divergence Angle and are emitted in almost parallel directions. Lasers emit light that is polarized in a fixed direction. A simple example illustrates this intuitively: lasers do not refract. Light waves are made up of innumerable photons of light. Due to the principle of resonance, the quantum of light emitted by the laser is consistent in wavelength, frequency and polarization direction, which makes it have a strong interference force. We also call it laser coherent light. This is because lasers are much more coherent than ordinary light sources.
