Laser beams have features as follows:
• Frequencies are smaller in width than other beams (sun and electric bulbs) and
phases are uniform so that high monochromatic and convergence performance
can be obtained and thin beams of light can reach places at a long distance.
• Being highly converged, the laser beams exert a heating action that may be
harmful to human body.
Reference: The laser beams of this laser printer are invisible rays.
