KYOTO, Japan, June 10, 2025 — Nuvoton Technology Corporation Japan (NTCJ) announced on January 15 the release of its leading indigo semiconductor laser, boasting an optical output of 1.7 W at a 420 nm wavelength. The new product and alternative solutions to mercury lamps will be presented at LASER World of PHOTONICS 2025 in Munich, Germany, from June 24 to June 27. The company welcomes visitors to their booth.

1. This product delivers an industry-best 1.7 W of optical output power at a 420 nm wavelength, similar to the g-line of mercury lamps, all within a compact TO-56 CAN package. The high output and compact size enhance the design flexibility of light source devices, enabling the creation of smaller devices compared to those using mercury lamps.

2. With over 40 years of experience and more than 3 billion semiconductor lasers shipped for optical discs, NTCJ possesses extensive design and manufacturing expertise in semiconductor lasers. The newly developed indigo semiconductor laser uses proprietary optical design and heat dissipation technology, achieving both high efficiency and long-term reliability. This reduces power consumption and the frequency of light source replacements compared to mercury lamps, thus lowering operational costs.

3. Emitting laser light at a 420 nm wavelength, close to the g-line of mercury lamps, this product can be combined with NTCJ’s mass-produced ultraviolet (378 nm) and violet (402 nm) semiconductor lasers. This combination serves as an alternative light source for the i-line (365 nm), h-line (405 nm), and g-line (436 nm) of mercury lamps. Moreover, adjusting the output power ratio of each semiconductor laser allows for highly flexible optical designs not achievable with mercury lamps.
