Nichia Develops Higher Power Green Laser Diodes
CompoundSemi News Staff
November 23, 2012…Nichia Corporation reports that it has successfully developed a high-power pure green laser diode which has optical output power higher than 1W with 525nm lasing wavelength. Nichia says that the laser will be applied to display applications such as Laser TV. Nichia reportedly optimized the epi-structures based on c-plane GaN substrates to achieve the improved performance.
Nichia says that as a result, the company’s new green laser diode achieved 10 times greater optical output power and 1.5 times higher Wall-Pulg-Efficiency*3 compared with the current lower power green laser diodes based on GaN. Notably, the high-power pure green laser diode development completes the fundamental three colors semiconductor laser light source with 1W range output power for each color. Nichia asserts that the three color laser light source will open the application of laser TV as well as laser projectors with the much lower power consumption and the higher color gamut.
