1.7 W 420 nm indigo laser diode enables replacement of mercury lamps

Nuvoton launched indigo semiconductor laser emitting an optical output power of 1.7 W and a wavelength of 420 nm. Advantages of this product claimed by Nuvoton include miniaturization, cost reduction of optical systems. Nuvoton suggests this LED can be combined with its mass-produced ultraviolet semiconductor lasers (378 nm) and violet semiconductor lasers (402 nm) as an alternative light source solution to mercury lamps, contributing to the realization of a sustainable society. Features: This product achieves an industry-leading optical output power of 1.7 W at a wavelength of 420 nm, close to the g-line of mercury lamps, in a compact TO-56 CAN package. Using this high-output, compact product enhances the design flexibility of light source devices, enabling the development of smaller light source devices compared to the mercury lamps. Realizes high efficiency and long-term reliability through proprietary optical design and heat dissipation technology, reducing the running costs of optical systems. By adjusting the output power ratio of each semiconductor laser according to the application, it is possible to achieve highly flexible optical designs that were not possible with the mercury lamps. Mercury lamps emit bright lines of light such as the i-line (365 nm), h-line (405 nm), and g-line (436 nm) [2], and are used as industrial light sources for applications ...
