Nuvoton Technology Corporation Japan Unveils New High-Power Violet Laser Diode

In a significant advancement for optical technology, Nuvoton Technology Corporation Japan (also known as NTCJ) has announced the launch of an industry-leading high-power violet laser diode. Scheduled for mass production in May 2026, this innovative product boasts an optical output of 4.5 watts at a wavelength of 402 nanometers. This represents a remarkable 1.5 times improvement compared to NTCJ's previous models, which operated at 3.0 watts.

Key Features of the New Violet Laser Diode

The 9.0 mm diameter CAN package (TO-9) houses the new laser diode, which utilizes NTCJ's proprietary device structure and advanced heat dissipation technology. This ensures not only extended lifespan and improved performance at high power but also contributes to a higher production throughput, particularly in optical equipment used for maskless lithography.

High-Power Operation Challenges Addressed

Historically, violet laser diodes have faced challenges such as low wall-plug efficiency and short wavelength-induced degradation, which have hindered stable operations at high power. NTCJ's latest product overcomes these hurdles through enhanced thermal conduction and improved electrical efficiency—capabilites derived from design strategies previously applied in their high-power ultraviolet laser diodes.

Applications in Semiconductor Manufacturing

The primary application for NVCJ's new violet laser diode lies within the realm of maskless lithography, a process critical for advanced semiconductor packaging. This method allows direct exposure of wiring patterns from design data, thus shortening development times and reducing costs. Moreover, the high optical output enhances throughput, which is especially beneficial for meeting the rising demands in AI-driven markets.

With recent predictions estimating a surge in maskless lithography applications, NTCJ's addition of a new 402 nm, 4.5 W diode aligns well with the industry's growth. This comes hot on the heels of NTCJ's 1.0 W high-power ultraviolet laser diode for i-line applications, demonstrating their commitment to developing versatile and high-efficiency optical sources.

Future Prospects and Exhibitions

NTCJ is excited to present this groundbreaking product at the upcoming OPIE '26 exposition, scheduled for April 22-24, 2026, in Yokohama, Japan. As markets evolve, the significance of laser diodes like the 402 nm violet variety will only increase, offering new possibilities in photocuring, 3D printing, and biomedical applications.

As advanced manufacturing demands become more rigorous, NTCJ is poised to provide essential solutions that not only meet but exceed current industry needs. Their ongoing research and development efforts highlight a robust commitment to innovation, ensuring they remain at the forefront of the optical technology landscape.
