No. 655: Developing a green semiconductor laser with the world’s highest light output (November 24, 2012)

Nichia developed a green semiconductor laser that has the world’s highest-level light output. By improving the design, the company successfully increased the current-to-light conversion efficiency by more than 50%. It can be used for video equipment like a high image quality TV. The company plans to mass produce the newly developed green semiconductor laser in 2013.

The newly developed green semiconductor laser has 14% current-to-light conversion efficiency with a light output of more than 1 watt. The existing product has 9.0% current-to-light conversion efficiency with a light output of 0.1 watt. The company increased the conversion efficiency by improving the quality of crystal with the help of the materials that it uses for its light-emitting diode (LED), blue semiconductor laser, and blue-violet semiconductor laser. Because red and blue high output semiconductor lasers are being mass produced, the company will have three primary colors for mass production.
