Nuvoton Releases 1.7 W 420 nm Indigo Laser Diode

Nuvoton Expertise Company Japan (NTCJ) introduced in the present day the launch of its industry-leading(*) indigo semiconductor laser, which emits an optical output energy of 1.7 W and a wavelength of 420 nm. This product contributes to the miniaturization and value discount of optical programs. Moreover, when mixed with our mass-produced ultraviolet semiconductor lasers (378 nm) and violet semiconductor lasers (402 nm), it serves instead mild supply resolution to mercury lamps, contributing to the belief of a sustainable society.

(*) As of January 15, 2025, primarily based on our analysis of semiconductor lasers emitting at a wavelength of 420 nm.

Achievements:

• Achieves industry-leading optical output energy of 1.7 W at a wavelength of 420 nm, contributing to elevated design flexibility and miniaturization of optical programs.
• Realizes excessive effectivity and long-term reliability by proprietary optical design and warmth dissipation expertise, decreasing the working prices of optical programs.
• By combining this product with current mass-produced merchandise, it’s doable to offer different mild supply options to mercury lamps.

Mercury lamps emit brilliant traces of sunshine such because the i-line (365 nm), h-line (405 nm), and g-line (436 nm) [2], and are used as industrial mild sources for functions resembling resin curing and publicity. Nonetheless, the mercury lamps have technical challenges together with giant mild supply measurement and excessive energy consumption. Moreover, since they use mercury, mercury lamps are topic to laws in Japan and different nations due to well being and environmental considerations. Due to this fact, different mild sources are anticipated to be developed.

Aiming to interchange the mercury lamps, we now have been creating high-efficiency and long-term reliability semiconductor lasers. We now have now began mass manufacturing of an industry-leading indigo semiconductor laser with an optical output energy of 1.7 W at a wavelength of 420 nm, near the g-line of the mercury lamps. This new product achieves each excessive effectivity and long-term reliability by proprietary optical design and warmth dissipation expertise. Moreover, by combining it with our already mass-produced ultraviolet semiconductor lasers (378 nm) and violet semiconductor lasers (402 nm), we will present different mild supply options to the mercury lamps, contributing to the belief of a sustainable society.

Particulars of the brand new product and different mild supply options to the mercury lamps shall be exhibited at our sales space at SPIE Photonics West 2025 in San Francisco, USA, and LASER World of PHOTONICS 2025 in Munich, Germany. We look ahead to welcoming you.

Options:

• Achieves industry-leading optical output energy of 1.7 W at a wavelength of 420 nm, contributing to elevated design flexibility and miniaturization of optical programs.

This product achieves an industry-leading optical output energy of 1.7 W at a wavelength of 420 nm, near the g-line of mercury lamps, in a compact TO-56 CAN bundle [3]. Utilizing this high-output, compact product enhances the design flexibility of sunshine supply units, enabling the event of smaller mild supply units in comparison with the mercury lamps.

• Realizes excessive effectivity and long-term reliability by proprietary optical design and warmth dissipation expertise, decreasing the working prices of optical programs.

With over 40 years of expertise and greater than 3 billion semiconductor lasers shipped for optical discs, we now have developed intensive design and manufacturing experience in semiconductor lasers. Our newly developed indigo semiconductor laser integrates proprietary optical design and warmth dissipation expertise, reaching each excessive effectivity and long-term reliability. In comparison with the mercury lamps, this reduces energy consumption and the frequency of sunshine supply replacements, thereby reducing the working prices of sunshine sources.

• By combining this product with current mass-produced merchandise, it’s doable to offer different mild supply options to mercury lamps.

This product, which emits laser mild at a wavelength of 420 nm near the g-line of mercury lamps, could be mixed with our mass-produced ultraviolet semiconductor lasers (378 nm) and violet semiconductor lasers (402 nm) to function different mild sources for the i-line (365 nm), h-line (405 nm), and g-line (436 nm) of mercury lamps. Moreover, by adjusting the output energy ratio of every semiconductor laser in accordance with the appliance, it’s doable to attain extremely versatile optical designs that weren’t doable with the mercury lamps.
