Despite his bold and unexpectedly accurate predictions, it has taken decades of continuous improvement before achieving productivity gains and economic growth. Similarly, the understanding of the dramatic development of high-power semiconductor lasers is limited. The industry first demonstrated the conversion of electrons into green laser pointer in 1962. Subsequent developments have led to significant improvements in the conversion of electrons into high-yield lasers.
These improvements can support a range of important applications, including optical storage, optical networking, and a wide range of industrial applications. A review of these advances and the many improvements it brings highlights the possibility that they will have a greater and more general impact on many aspects of the economy. In fact, with the continuous improvement of high-power semiconductor lasers, the scope of important applications will increase and it will have a profound impact on economic growth.
History of high-power semiconductor lasers. On September 16, 1962, a research team led by General Electric’s Robert Hall demonstrated the infrared emission of gallium arsenide (GaAs) semiconductors, which have “strange” interference patterns, meaning coherent lasers-the first The birth of semiconductor green laser pointers.
