Blue-green optical semiconductor laser pointer will be localized. The reporter learned on the 1st from the Suzhou Institute of Nanotechnology and Nanobionics of the Chinese Academy of Sciences (hereinafter referred to as the Suzhou Institute of Nanotechnology of the Chinese Academy of Sciences) that the Institute cooperated with many enterprises to establish the first gallium nitride-based blue-green semiconductor laser material and device manufacturing enterprise . This means that the monopolized blue-green semiconductor laser will be localized. GaN-based blue-green semiconductor lasers are an important direction for third-generation semiconductor materials.
Although it is currently emerging in the market, it will be closely related to your life in the future, such as large-screen laser displays. Zhang Shuming, a researcher at the Institute of Nanotechnology, Chinese Academy of Sciences, said that laser display is a new display technology after black and white display, color display, and digital display. It has many advantages such as large color gamut, high brightness, low energy consumption, long life, and no pollution.
Because laser pointers have important strategic significance, the Outline of National Medium- and Long-Term Scientific and Technological Development Planning (2006-2020) incorporates laser display technology into the development direction of national strategic emerging industries. “The core components of laser display include red, green, and blue primary-color semiconductor lasers.” Zhang Shuming told the Science and Technology Daily reporter that red-light semiconductor laser technology is relatively mature, and blue-green semiconductor laser technology is more difficult.
