Up to six processing stations can be supplied by a single laser.They suggest white lasers could be used in Li-Fi.The researchers had to pump electrons into the semiconductors with an additional laser light.It has been considered is an adjustable axicon able to transform a Gaussian laser beam into a dark hollow beam.Fiber-optic laser beam delivery is commonly used in industrial laser systems.
