The prosperity of the telecommunications industry brought by it is far-reaching. Take one of the first pioneers in the high-power semiconductor green laser pointer industry as an example. Founded in 1983, SDL is a joint venture between the laser brand (spectral physics) and Xerox of the Newport Group in the United States. Five years later, SDL was sold to JDSU for more than $ 40 billion during the peak of the telecommunications industry, one of the largest technology acquisitions in history.
Soon after, the telecommunications bubble burst, destroying trillions of dollars of capital, and is now considered the largest bubble in history. 2000s: Lasers became a tool. Although the burst of the telecommunications market bubble is extremely disruptive, the huge investment in high-power semiconductor lasers has laid the foundation for wider adoption.
As performance and cost increase, these green laser pointers are beginning to replace traditional gas lasers or other energy conversion sources in a variety of processes. Semiconductor lasers have become a widely used tool. Industrial applications range from traditional manufacturing processes (such as cutting and welding) to new advanced manufacturing technologies (such as additive manufacturing of 3D printed metal parts).
