Strained_quantum-well_laser Knowpia

A strained quantum well laser is a type of quantum-well laser, which was invented by Professor Alf Adams at the University of Surrey in 1986.^[1] The laser is distinctive for producing a more concentrated beam than other quantum well lasers, making it considerably more efficient. The lasers are notable for usage in CD, DVD, and Blu-Ray drives as well as applications in supermarket barcode readers and telephone optical transmission.^[1]
