Nuvoton's Groundbreaking Innovations in Light Sources

Nuvoton Technology Corporation Japan (NTCJ) has made headlines with its plans to showcase the latest advancements in semiconductor laser technology. From June 24 to 27, 2025, NTCJ will be attending the LASER World of PHOTONICS in Munich, Germany, where the company will reveal its revolutionary alternative to traditional mercury lamps—a high-performance indigo semiconductor laser.

What’s New: The Indigo Semiconductor Laser

Announced on January 15, 2025, the indigo semiconductor laser is a significant leap forward in optical technology. This compact device boasts an impressive optical output power of 1.7 watts at a wavelength of 420 nm, making it a viable alternative to the mercury lamps commonly used in various industries. The new laser design enables the creation of smaller and more efficient light source devices, which is an essential consideration in today's fast-paced technological landscape.

The indigo laser has the potential to reshape the way many light sources are built and utilized. It promises increased design flexibility for manufacturers, enabling them to develop solutions that are both compact and powerful. As traditional lamps face scrutiny for environmental concerns and inefficiency, NTCJ emerges as a pioneer in providing sustainable lighting alternatives.

Industry-Leading Expertise

NTCJ brings a wealth of experience to the market, having shipped over 3 billion semiconductor lasers for optical disc applications over its 40 years of operation. This extensive background equips the company with deep design and manufacturing expertise, which it leverages in the development of the indigo laser. With this new technology, NTCJ aims to set a new standard in efficiency and long-term reliability in light sources.

One of the standout features of this new laser technology is its proprietary optical design and advanced heat dissipation technologies, ensuring reduced power consumption and longer lifetimes for the light sources it powers. This translates to decreased operational costs, addressing a significant concern for businesses relying on these technologies in their operations.

A Versatile Alternative

The indigo semiconductor laser is designed to work harmoniously with NTCJ’s existing ultraviolet semiconductor lasers (378 nm) and violet semiconductor lasers (402 nm). This compatibility allows users to create a comprehensive light source system that can replicate the full functionality of traditional mercury lamps, covering the i-line (365 nm), h-line (405 nm), and g-line (436 nm). Adjusting the output power ratios of the different lasers gives designers unprecedented flexibility, enabling customized optical applications tailored to their specific needs.
