RE: LASER COMMUNICATION: This is wireless community through free space. Look at the red beam down there
Laser communication? How do they do that. Thought lasers burn. How is the information trapped in it
Yes laser burn but this work laser similarly to fiber optic links, except the beam is transmitted through free space. Before turning on the laser pointer, always be sure that it is pointed away from yourself and others.
Never look directly into a laser pointer.
Never direct a laser pointer at another person.
Follow the same rules for direct reflections of laser light from reflective surfaces.
The place where the beam follow must be free space to avoid damage to the eyes whiech can be permanent.
Wow... Thanks for this sir
