Semiconductor laser is the cornerstone of modern laser and optoelectronics industry, and it is a high-tech industry, so it urgently needs to be developed in China. In recent years, the global laser industry has been developing rapidly, and China has occupied more than a quarter of the total. The direct application market of semiconductor lasers accounts for 50% of the total laser market. The development of semiconductor industry in China is seriously lagging behind. Semiconductor laser industry chain: chip upstream, core component packaging and module middle, system integration downstream. The commercial chip and core component products are the short board of the development of domestic related industries.
