What if I told you that a laser can reach the earth all the way from space? You’d think it’s pretty cool right? Well it just so happens to be completely true! Scientists have created lasers to communicate from basically anywhere, and I’m here to tell you how it works. A laser shoots out a diverging beam that goes through the transmitter lens that creates a “well focused beam”. The well focused beam then goes through the receiver lens into the receiver diode. This is called laser communication. It is wireless connections through the atmosphere. DVD players work with the use of a modem-like device called a transmission module. This converts digital signals to LED or laser light. This light then travels through a fiber optic cable to the destination
