Blue-green semiconductor laser will be made

Science and Technology Daily Beijing, February 1 The reporter learned from the Suzhou Institute of Nanotechnology and Nanobiology (CAS) on the 1st of January that the institute, in cooperation with a number of enterprises, established the first gallium nitride gallium nitride Green semiconductor laser materials and devices manufacturing enterprises.

This means that blue-green semiconductor lasers monopolized by foreign countries will be domestically produced.

Gallium Nitride-based blue-green semiconductor laser is an important direction of the third generation of semiconductor materials.Although it is emerging in the market, but the future will be closely related to you and me, such as large-screen laser display.

Zhang Shu-ming, a researcher at the Suzhou Institute of Nanoscale Sciences, Chinese Academy of Sciences, introduced laser display as 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.

Due to its strategic importance, the "National Medium and Long-term Plan for Science and Technology Development (2006-2020)" integrates laser display technology into the development of national strategic emerging industries.

'Laser display of the core devices, including red, green and blue tricolor semiconductor laser.' Zhang Shu Ming told Science Daily reporter, red semiconductor laser technology is relatively mature, blue-green semiconductor laser technology more difficult. Previously only Japan and Germany Two companies to achieve blue-green semiconductor laser production.
