Nichia's RGB Lasers, Manufactured In-house

Nichia operates a unique in-house production system that manufactures all three primary colors—red, green, and blue (RGB) semiconductor laser chips. Utilizing the most advanced laser oscillators and processing evaluation equipment, Nichia delivers products with superior quality, cost efficiency, and stable supply, meeting the diverse needs of customers across industries. The "QuaLas™ RGB" laser product, featuring RGB LD chips densely mounted in one small package, has been installed in many projectors, making them more compact, with higher image quality and brightness.

Differences Between LEDs and Laser Diodes

Laser Diodes (LDs) have excellent light gathering properties due to their narrow beam radiation and small emission area, whereas LEDs emit light over a wide area The light density of LDs reaches 100 to 1,000 times or more than that of LEDs. Furthermore, LDs feature a narrow spectrum and excellent monochromaticity, providing high color reproducibility. LDs also maintain a high optical output even at high currents compared to LEDs.

Eco-Friendly Next-Generation Light Sources

Laser diodes (LDs) are used as alternative light sources to mercury lamps in various fields, including photolithography applications in manufacturing processes and projection applications. Replacing mercury lamps with LDs not only resolves the environmental issues caused by disposing of mercury, but also contributes to reducing power consumption and CO₂ emissions with its high energy saving performance.
