China has rapidly become one of the world’s most important hubs for semiconductor laser diode production. With a strong supply chain, advanced epitaxy and packaging technology, and a growing domestic market, Chinese diode laser companies serve customers worldwide in industrial manufacturing, medical aesthetics, communications, et recherche scientifique.
Parmi eux, Vivlaser stands out because it focuses on semiconductor laser diodes and pump sources as its main business, while many other companies treat diodes as only part of a larger ecosystem (par ex., fiber lasers or system integration).
