Nuvoton Technology Launches Revolutionary Indigo Laser Diode

Nuvoton Technology Corporation Japan (NTCJ) has made significant strides in the semiconductor laser market with the launch of its latest product, a 1.7 W indigo laser diode, designed to emit light at a wavelength of 420 nm. Announced on January 15, 2025, this advancement promises to enhance the light source solutions available to industries reliant on precision lighting, including those traditionally dependent on mercury lamps.

Industry-Leading Technology

The new indigo semiconductor laser diode stands out with its remarkable optical output power of 1.7 W, making it one of the most efficient devices in its category. This compact technology, housed in a TO-56 CAN package, offers a significant reduction in size compared to earlier mercury lamp-based solutions, thus allowing for greater design flexibility. With this capability, manufacturers can develop smaller light source devices that were previously challenging to design, all while maintaining performance and reliability.

A Legacy of Excellence

Building on over 40 years of experience, NTCJ has successfully shipped more than 3 billion semiconductor lasers for optical disc formats. This wealth of experience is pivotal to the advanced engineering seen in the new indigo laser, which incorporates proprietary optical designs and advanced heat dissipation technology. The result is an innovative solution that not only enhances efficiency but also prolongs the lifespan of the diode, translating to lower replacement costs and power consumption over time.

Versatile Application Potential

The 420 nm wavelength of the new diode closely aligns with the g-line of mercury lamps, providing a powerful alternative for a range of applications. Additionally, NTCJ plans to showcase this product as part of broader alternative light source solutions at upcoming exhibitions, such as SPIE Photonics West 2025 in San Francisco and LASER World of PHOTONICS 2025 in Munich. At these events, the company will demonstrate the integrated capabilities of its indigo laser diode alongside other wavelengths, such as its ultraviolet and violet semiconductor lasers.

The versatility of the new product allows users to create flexible optical designs previously unachievable with mercury lamps. Furthermore, by adjusting the output power ratio among various semiconductor lasers, operators can fine-tune their applications for optimal performance, catering to the diverse requirements of different sectors.
