Contextual analysis

THE PROBLEM OF ELECTRONS COLLIDING WITH ATOMS IS STILL A PROBLEM IN LASERS (SCIENTISTS CALL THIS EFFECT "PHONON EMISSION"), BUT IT'S NOT AN INSURMOUNTABLE OBSTACLE. Since LASERS ARE CONTROLLED SOURCES OF VISIBLE LIGHT, THEY CAN BE USED TO SEND INFORMATION SIMILAR TO HOW RADIO WAVES CARRY INFORMATION. IN FACT, FIBER OPTIC CABLES CONTAIN INFORMATION-CARRYING LIGHT BEAMS THAT WERE CREATED BY LASERS (ALTHOUGH, MOST OPTICAL FIBERS USE INFRARED LIGHT RATHER THAN VISIBLE LIGHT FOR EFFICIENCY REASONS). LASERS CAN ALSO BE USED TO SEND INFORMATION-CARRYING VISIBLE LIGHT THROUGH FREE SPACE. THIS SET-UP IS CALLED OPTICAL WIRELESS COMMUNICATION.
